The only times I eat out are when I visit my daughter or son and I enjoy those times.
Since I live alone in Fresno, the only place I go is a very rare trip to In-N-Out Burger. Usually as a treat. Stopped there after my MRI a few months ago.
Back when I was working I frequently went on business trips. I got used to eating alone because getting room service and eating in the hotel room alone bothered me.
It's so expensive now days, even the 'fast food' joints charge almost as much as a sit down restaurant, well, at least in Southern California. Still, we do enjoy the occasional dining out. I'm retired and she soon will be, so money is an issue and eating at home is definitely less expensive but I'm sure we'll continue to occasionally treat ourselves .
