Ordering Milk?

Is it crazy to order milk while at a restaurant? My co-workers was laughing at me when I decided to order milk at dinner. Even the waitress was joking that the last time someone order a glass of milk was last week and he was 80 years old.

It didn't exactly go well with the pork chops that I ordered. My reasoning for ordering milk is that with the amount of traveling I do, there is no point for me to buy milk at home. It would spoil by the time I get home again.

And I don't want to get any shorter than I am already... :P
