I worked here as a seasonal colleague for Christmas 2013
In a shift we're given a split rota, so I spent 1/2 hours on till and 1/2 hours on the shop floor handing out promotional leaflets to customers as they enter the store, offering assistance, folding T-shirts (which is annoying because customers ruin your time spent folding within minutes, where the supervisor would call us back to fix again and again) and facing up products when necessary.
Hardest part of the job would probably be removing the security tags, I never quite caught on how to remove them.
Also finding games behind the counter was difficult at times as there's not much space to move past staff at the till. Half the time the game had sold out upstairs so had to run downstairs to fetch the game.
My co-workers were extremely helpful, always willing to help out when we were struggling how to use the computer stock check screen, mostly using f1 keys etc.
Sometimes you might get called to help in the stock room with price tagging items for promotion sales/ regular prices. Or asked to help out in finance office, which I'm unsure of the duties for that.
Friendly staff with common interests, always kept busy
Finding stock in the warehouse, getting asked to work a different department you're not familiar with.
