On Easter Sunday I took my wife's parents out for lunch with my wife and our two kids. I paid for the meal and all drinks but when it came to the tip, I was expecting some sort of contribution and was a bit shocked when nothing was offered.
Then on Wednesday evening I took a group of 14 people out for a meal following a family event. The country house we went to was fairly expensive and again, I was shocked when no one made any contribution to the tip and left me to take care of it.
Personally, if I had been fed at someone else's expense I would at least contribute to the tip so as not to appear a complete freeloader. Am I wrong to be peeved?
