The person on the till
Last night at the French conversation group one of the things we talked about was shopping, particularly in supermarkets, and one of the words we weren’t sure of was till / cash register. I now know this is la caisse (enregistreuse) or le tiroir caisse and that someone who works on a till is possibly un caissier or une caissière.
This got me thinking what you call such a person in English. You might call them a shop assistant or maybe a cashier, but neither of these seems to fit the job very well.
What would you call such a person? Would the term you use depend on the kind of shop?
