On the cost of fast food: it's still possible to save money depending on where you go, what you order, and how big your appetite. My appetite is not as great as it used to be do sometimes I order off the kid's menu. Other times, I will select a few low cost items that suit my tastes. Also, I often take good home and avoid the $3 sodas. A local DQ still has a combo mess as l for $6-7 with burger (or chicken of steak fingers), fries, drink, & ice cream. It's on the kid's menu but it satisfies. Similarly, I can get a decent meal at Sonic for less than $10 by taking it home. If one is creative, one should be able to do something similar at almost any fast food place.
Another way to save: get the app on your phone and take advantage of deals & rewards. My Mom had a McD's breakfast sandwich for $2.50 this morning.
