Yes and no...
I work on a drilling rig, and so I'm far away from home about 2 weeks a month. When I am at work, I get $50-75/day for food (seriously overkill, since I most often grocery shop and cook for a week, on what I am paid per day). Often I am in the middle of no where, so I have little opportunity to spend my money, even if I wanted to (unless I do some internet shopping, which I rarely do now). I drive a used vehicle that I have paid off, and we are all paid varying degrees of what people would consider a good income, and I see lots of people I work with, struggling to make ends meet, because they have financed a new truck every other year (or every year for some) and all the recreational toys (boats, quads, guns, etc).
I do eat out when I get a chance at work, because it is a good mental break to get away, and I find that when I am home, I do eat out more often than I should, as a way to maintain business contacts, and old work friends from before I moved to the field. Sometimes I find myself in the trap of buying things because I can, and not because I need them (such as clothing), but I'm making a much more conscious effort not to.
I am also able to hammer away at my mortgage, and my husband's student loan because of how much I can bring in, which we wouldn't be able to do, if I was still in an office position, making $70,000 less a year.
