Michael notes that this was spotted at "the famous, customer unfriendly Lorenzo's Pizza on South Street in Philadelphia." I don't know what people really take when they ask for a "cup of ice" but Lorenzo is on to them.
I don't usually post the following: newspaper headlines, personal email, craigslist postings, unprofessional websites. I also tend to not crosspost things from other blogs, since I have so much unique material waiting for me to get to it.
Things I see a lot: silica gel "do not eat"; hair dryer labels; inside the bus "do not drill"; Wal-mart sign about IDs; coffee machine with "2" cup sizes; employees must "wash hands".
