It appears that nobody is safe from clamping - even friendly tour companies.
Viking Splash Tours got a nasty surprise this morning when they found their tour bus had been visited by clamping elves overnight.
The company tweeted from @VikingSplash: "We got clamped (whoops) #ParkingFail"
The company then received messages from sympathisers this morning, with some followers saying "we feel your pain".
Viking Splash Tours is one of Dublin's most novel tour companies - with tours over land and water.
