I'm sorry but I also find it rather extreme to have him arrested. OK, if he/they were not satisfied with the meal or service, they should have spoken up but who knows, by that time, they may have got so fed up with everything that it all turned very negative.
We have all been there when we have had terrible service, meal etc and we just want to go and get away from the place a.s.a.p.
Is it actually a crime and where they/he actually breaking a law?????? I always thought you could only be arrested if you had actually committed a crime but maybe in our so-called civilised societies, we are also losing that right too now.
