I have never ever seen anyone scrabble around to pay €30,44 - since the convention would be to round up anyway.
Yes, I think some of the people on this thread (as well as the bill-splitting public shamers) are imagining - or claiming - people are quibbling over pennies. In fact, in some cases, people's bills double or treble or more, when the bill-splitters' subs kick in.
Also, I don't get people suggesting that everybody's bills at the same restaurant will be much of a muchness; unless it's a 'restaurant' like McDonald's, there will still be a big range of cost options on the menu, particularly with the drinks. Even if a place only served one meal and one drink option, somebody could still have two of them and then owe twice as much as everybody else!
I don't get to go out for meals very often, so when I do, I have a huge blow-out slightly more than an elegant sufficiency. Of course, I chose to spend more, so I pay more: that's a given. I can't begin to understand people who don't just not insist on paying more for their own extra costs but actually insist that others must.
