Factual error: When Hap goes to the grocery store to buy beer, it shows signs of a grocery store selling beer, liquor, cigs, milk and bread. This doesn't exist in Texas. Liquor is not sold in grocery stores. And liquor stores (only sell alcohol, no groceries) would close at 9 pm and this is after that since everyone was asleep.
The Bottoms - S1-E2
Continuity mistake: When Leonard leaves to see his uncle, his hat is on backwards for 2 shots.
Factual error: Hap is sending a package to Houston, Texas but the zip code he writes is "89921." This isn't anywhere near Houston. At best it's El Paso, although 89921 isn't in use. (And if his 5s look like 8s, "59921" is in Montana).
