That is awesome, I can just imagine being there hearing that, I would have been laughing my head off. It kind of reminds me how quick witted two elderly Nuns were on the bus in Perth many years ago when they were standing when they boarded as no seats were vacant, one of the nuns asked 2 young girls to stand for them and one of the girls with attitude said she's not standing for two old bags, I think everyone was in shock hearing that, then one of the old Nuns said, well young lady unless you've made reservations to die young, your going to be an old bag one day to.  I thought how amazing was her come back and fast, just like the senior in your post....Kisha
