Like djk7 I don't mind eating alone. Wasting 1+ hour of my time is what irks me. So I'll usually do a sit-down dinner once and the rest of the week I'll get take-out from the nicer restaurants but rather waiting for them to make the meal, I'll usually spend the time shopping at the adjacent mall or Best Buy or something.

A guy from another facility got sick from eating at a commercial restaurant once. So now, he NEVER eats out. Instead, he'll go to places like Fresh & Easy or Whole Foods Market and buy some of their fresh, quick meals and then cook them himself at his hotel.
