Nah - I'll just tell them who did it, so just don't be surprised if you go out to bring in your bin next week and there's more stuff in it than when you put it out.
I don't drink the stuff myself, but while here's the reasonable possibility that
none of them drink Guinness (my tipple), there's a stronger likelihood that at least one of them can handle something generic like Foster's.
It's not something I do every year, but they helped out beyond the normal call of duty a couple of times last year.
