Pros
Your co workers will be some of the most supportive and hardworking people you'll ever meet, and all in store staff and managers are lovely. Due to the experience I have gained by working shifts in myself and being responsible for the whole store (despite only being a part time sandwich artist) I'm able to apply for shift supervisor jobs at other chains. At least the experience can bring you far.
Cons
At the particular franchise I work at you get paid minimum wage but still have responsibilities of a manager. You'll regularly be completely alone in the morning and night shifts, leaving you with way too much work for one individual, even if you're not fully trained you'll be responsible for ensuring the right float is in the till every morning and night. Every missing coin, and food wastage will be taken out of your already little wage. Skeleton crew even on a Saturday, and there is no extra pay for working Sundays, bank holidays, or over time.
