I was out getting food with a pal once and we went for do-nuts because it was early. As we were standing in line she turns to me and says "isn't it stupid that they have "dozen" on the menu twice, with two different prices?" And proceeded to revel in her own intellect for spotting the "mistake".
When I looked at the sign for myself I saw that on one side they had the regular "dozen" and on the other they had a "baker's dozen". I was quietly snickering to myself, but didn't have time to say anything because by then we were at the register. It's a bit sad how things like that aren't common sense with some people anymore.
Some people... >.>
