So upon returning, my face fell when I noticed that one of the three envelopes I got back was very thin-- a sure sign that something had gone wrong with the pictures and we had lost a full roll. I asked the woman if I'd have to pay for the third envelope and she said no, of course not, not if they messed it up.
I opened the envelope in front of her (to verify that the pictures hadn't been processed) and they hadn't been, of course, because it's very difficult to process pictures from a half-roll of lifesavers.
No, seriously. I am seriously that cool.
