Casey's Pizza is still good in my neck of the woods. My wife doesn't agree, but I find it superior to all of the other chainy-quick places like Papa Johns, Pizza Hut, Dominos etc. Single slices are all still respectably sized too. Expensive yes, but they aren't tiny.
The gas stations quality is determined by where they're located IMO. We've got 4 in town, and 2 are in parts of town suffering from low socioeconomic conditions. I avoid those, because they are generally dirty, have vandalism and/or damage, and you can walk into one and count the number of teeth other folks have on one hand. The other 2 are in better parts and in more updated facilities and have much better upkeep and staff that actually care or at least fake it well enough.
