while we're on a roll...
...of (boring) stories that demonstrate how dumb i am:
1) my senior yr of HS we toured the local community college on Career Day. when we arrived we were told to note the number of the bus, and be back by 4pm because the bus was leaving at 4:15 sharp.
when i got thru all the exhibits, i walked back to the bus lot, took a seat next to bus #328 (or whatever) and read a paperback book. eventually i noticed that it was past 5pm and my bus was still empty. because, of course, it wasn't my bus.
somehow it never occurred to me that there would be more than one bus #328, in spite of the fact that all kinds of school districts had bussed their kids there that day.
i think some nice student gave me a ride back to town. i really don't remember, but i'm pretty sure i got back because i'm not still there.
2) i had a Subway discount card that gave you a free 6" sandwich if you bought 5 at regular price.
i bought five 12" sandwiches, and couldn't understand why the manager didn't want to give me the free sandwich. she was very nice, but she was adamant that it only counted if i bought five 6" sandwiches, not 12" ones.
i was equally adamant that that was stupid because i was buying even *more*, so why shouldn't i get the free sandwich.
eventually she said "i guess i can't explain it to you, but i'll give you the sandwich because i don't want to argue with you." which was a good business decision, because it kept me coming back to the store.
after i left, it finally occurred to me that the reason they can give away a sandwich if you buy 5 6" ones is that they have a higher margin built in. they make less profit on 12" sandwiches, which is why they don't count in the promotion. duh.
