I don't have anything constructive to add, but this is one of my biggest problems to. Except for it's "How do I go to lunch with people (from an old job)?" We both barely have time to fit lunch into the hour break with a car, and we aren't particularly close - it's so annoying when they call me out of the blue to ask about going to lunch and I'm like "I, uh, don't have a car today".
