Pros
If you've done some time, you will be in a familiar environment. If you are attentive, you may observe the business operations equivalent of an alligator death-roll and apply that insight somewhere where you will have the agency to improve systems and maybe even use the restroom or see the sky in daylight without permission.
Cons
There is excrement on the walls, customers are understandably irate, policy forces both staff and management to prioritize avoiding consequence over performing to their capabilities, every system is cumbersome and inefficient, trust and respect are nowhere to be seen. For example, a cashier may not open the till, void items, process discounts, access the ill-conceived inventory management software, do many basic POS tasks, or even conclude a transaction. Managers must be summoned to perform these tasks, as a cashier with this company is apparently only trusted about 1/100th as much as a gas station attendant. Branch management is socially inept, rude, and transparently self-interested. Non-management is unionized, but 315 does not seem to have any teeth. 12-15 hours of your day may be dedicated to this enterprise.
