It's just part of the evening's games isn't it, we usually play about 24 songs through 2 sets plus 2 or 3 encores . We make them work for em, you know "we can't hear you" "are you sure you want another" "We have got to get the half eleven bus you know"
Generally consists of upbeat sing along type numbers... Crazy little thing, Brown eyed girl, All or nothing... you know the type
To me there is no problem with them as you account for them in the timings of your sets good time to get them to remember how good you were and that they had a real good night and the band played 3 encores for us
