My point about 'professionalism' was really that in my view, a break between sets should be 20 minutes max, maybe 30 at a stretch for a relaxed charity gig, but any more seems counter productive, as you have got the crowd warmed up and into it, and then they go cold, before you start again.

Professionalism is doing exactly what is asked by whoever is paying you.
