Help gift etiquette question: staff at ensemble group

[Wiifitmama]

My teen son attends an ensemble group once a month weekends. The last session is in a week and they are doing an end of term concert. Do I send/bring staff presents? Boxes of chocs or something? Or once they are teens do you not do that? I am clueless what the etiquette is!!! Help! I think there are 3 staff there.

Bump

Any thoughts?

I don't think I would, can't think of a good reason why not, just that the need to do it seems to wear off as they get older. What does DS think?
