It appears that you cannot afford a $15 lunch and you are flustered by that.
OK then, do this: Find lunch counters that'll serve you lunch for less. Or.....
.....or pack your own lunch. Or.......
.....skip lunch and diet a bit. Or......
......apply for one of those $16 an hour gigs and supplement your Social Security monthly check.
It ain't rocket-science, poster BS.
I simply takes someone with gumption, a willingness to work for living, and be disciplined about it all.
Think of it as "The American Way".
