Putting the money in the till
Literally unpacking delivery - managing shop floor - upsellimg promotions and being on the tills, when closing you have to restock on your own and sweep up, manager will be doing closing emails and stuff. If you're a temp you might not get many shifts (usually 4 hours each) so be aware of that. Fun place to work though - not to strenuous.
