So you're at a bookstore where they sell custom CDs...

[Deja Q]

Where you sit at a terminal and pink'n'choose the songs.

Is it unreasonable to have time limits when all the stations are being used and people are waiting?

And, under those circumstances, if you get out of your seat do you then forfeit your turn?

Not that I cared, I was more interested in the overpriced DVDs. But I made a mental note of things and was both amused and bemused by the people there. Mostly bemused, it seems most of them preferred to listen for 45 minutes rather than buy. :D (which in turn is not a bad thing as far as I'm concerned...)
