I would be very upset about the lack of response for the email as well but I'm not sure I would be as upset about the whole incident as you were. Honestly my first thought when I read this letter was to do a search on google for fast food places near where I was, find one that I knew had a dollar menue, go there, get some dollar menue items, come back, and eat. Or if the kids were really starving, let them go with and eat in the car on the way back to the hotel. Usually though if we were that strapped for cash we took stuff for sandwiches with us and ate them instead of eating out or incase something went wrong or places were packed.
