Heh...here's a funny story...
When you go to get your taxes done with the volunteers, you can either just walk in or make an appointment. Of course, if you make an appointment, you get to walk past anyone who might have walked in. I did make an appointment one year. So I went to the senior center (which, by virtue of where it just happened to be taking place) was full of elderly walk-in folks. When they called my name for my appointment, I passed up a bunch of these old folks (mostly women).
They were FURIOUS!! Audibly complaining about how disrespectful I was not letting the elderly go first!!
I swear, I never made an appointment again! Those elderly folks are so pleasant to sit there and visit with...no need to hack them off! Heh heh!
until you hack them off, that is. :P
