My experience, every cashier has different rules not every store,
cashier 1: we can only do 1 transaction a day in this store,
cashier 2: you can only use a credit card with your name on it and it has to match your ID,
cashier 3: I can do as much transactions as you like up to a total of 999,
cashier 4: was ready to do as much as i wanted and how i wanted,
So in the end of the day, every cashier has their own store policies and rules.
