When it's your birthday, who pays the bill if you're going out for lunch/dinner with your friends?
I'd like it best if everyone paid for exactly what they ordered, including me. If a person/people are kindly paying for another who wouldn't have been able to afford to come otherwise, then that's absolutely fine, of course. I just definitely wouldn't want to divide the total equally, because you know some cheeky sod is going to take advantage.
