They say "the best revenge is to live well", and what better way to do that than to go shopping?
A peculiar phenomenon is sweeping Asia as people emerge from lockdown into their deserted cities.
Take the flagship Chinese store for French brand Hermes in Guangzhou as a case in point. It counted $2.7m (€2.45m) in sales on the day it reopened in April - the biggest single-day takings at a luxury outlet in China.
The retail upswing is called 'revenge shopping' - an overindulgence by people who have missed their favourite outlets due to lockdown - and it's taking the world by storm.
In cities across China and India and in Singapore, long queues are forming outside outlets such as Apple, Nike, Gucci and Lancome, and economic expert Jim Power said Ireland can expect a repeat performance: "There is a view out there that everything will be dead forever but for a lot of people the animal spirit will take over and they will be straight back on the street as quickly as they possibly can.
"Spirits are low and anything that will rekindle it has to be welcomed - the Asians are embracing it and I have no doubt we will embrace it in Europe and Ireland too."
Despite the uncertainty in the coming months, Mr Power predicted two key factors will influence people's retail sprees.
"First of all, psychologically it's good for people. Puritans might describe it as 'conspicuous consumption' but a lot of us enjoy it and it lifts the mood. There is a reason its called 'therapy' - people feel it can be good for their sense of well-being.
"Happiness is made up of a lot of different things - family, exercise, reading and so forth - and part of that is going into shops and looking and buying stuff. And if it makes people feel better, great, if it keeps people employed, then all the better."
The second factor driving the craze, Mr Power said, is that people have built up a nest egg because they are spending less on commuting, restaurants, drinking out, beauty treatments, the gym, holidays and hobbies.
"Over three months, a lot of people's incomes haven't particularly suffered because of Government support schemes and a lot are still working without the opportunity to spend it. So clearly there is going to be a significant build-up of personal savings during this period and that will spur people back to the shops."
On what people have managed to squirrel away, he said: "Over a three-month period, I would say people will have been able to save around €1,000 or €2,000."
Mr Power believes that talk of economic uncertainty will not deter people from buying their little luxuries.
"The period that we are living through has been incredibly tough on spirits and on the mind. And people are missing the stuff they would normally do, so the first opportunity they get to remedy that, they will take it. There is no doubt in my mind, if the pubs were to reopen tonight, they would be packed.
"A lot of people will feel 'we made a lot of sacrifices, we suffered, it's time to reward ourselves'."
Some retail outlets, such as those on the high street, may benefit from the first flush of binge-buying, but others will miss out on the surge because of the Government's summer-long five-phase plan.
Those that will remain in lockdown until the end of July and August include large shopping centres, hair salons, gyms, pubs, bars and nightclubs.
That prospect has caused some to call on the Government for an early release date. LVA chief executive Donal O'Keeffe recently said pub owners should be treated the same as cafes and restaurants.
"We fully respect the need to continue to protect the public health," he said, but he added: "If other venues who serve food and alcohol are allowed to reopen in phase three, then pubs should be granted the same opportunity to trade."
