I'm starting my first full week on Sunday after a week off because I wasn't able to get on the previous schedule. My question is are cashiers allowed to have water bottles at their register during their shift? For my first shift I brought a clear plastic water bottle because during my training shift my mouth got so incredibly dry and the drinking fountain was out of order. My TL came up to me and said we aren't allowed to have water bottles at our register. Is this a real rule? I think it seems kind of silly.
