It is revealed that Glenn has stashed away $27,000 from the store's maintenance fund for a rainy day. In Lost and Found (2017), there wasn't even enough money in the maintenance fund to patch up the break room ceiling.
When Amy is talking to Laurie at the end, Laurie's legs keep changing from being crossed one way and then another.
When Amy is speaking to Laurie about interviewing, the way Amy holds her clipboard changes repeatedly between shots.
When Garrett is talking to Cheyenne in the dairy section, trying to remember the name of one of the actors in The Hitman's Bodyguard, Sarah can be seen in the background kneeling to stock a shelf, helping a customer, then having the customer walk away and her go back to kneeling multiple times with the same customer.
When Amy is being interviewed for the manager's position, a stack of papers alternates between being on the desk and on her lap between shots.
As part of her interview, Amy explains that she reorganized the women's wear section to make certain items easier to find. In big box retail stores, all shelf and department layouts are determined by corporate. An individual employee at one location rearranging things would technically be insubordination, not a strength to be brought up in an interview.
Glenn drives his car through the front of the store but there isn't so much as a scratch or dent on the car afterwards.
Glenn, Mateo, and Jonah reason that they must spend the $27,000 Glenn took out of the maintenance fund, or else corporate will notice it missing when they audit the store's finances. The money has already been taken out of the maintenance fund. Whether they spend it on maintenance, or anything else, or nothing at all, the information in the store's accounts won't change. Furthermore, corporate would have no way of knowing Glenn hadn't spent it on maintenance over the years, and suddenly spending $27,000 the store shouldn't have on maintenance would likely raise red flags.
Dina suggests Amy confront Laurie or else she'll go to corporate and tell them about "her little nepotism hire." Blaine's hiring paperwork would have to have been submitted to corporate, so there's no way they wouldn't already know.
