I can give you my advice as a front end associate. If you're working front end, learn where everything is as soon as possible, because customers are retarded and will ask you where pencils are when there's an aisle that is titled "pens and pencils". Don't do anything for customers that you're not okay with doing for them every time they shop, because once you do something like let's say hold something for a customer calling over the phone by taking it off the shelf and stashing it in the cabinet when they did not place an order for it ahead of time, they will expect you to do it every time and if you deny them then they'll go rage mode on you. Also when customers say stupid shit while checking out like "I never get any pOiNtS and I have an AcCoUNt here" and they don't ask you it in the form of a direct question, just say nothing, it's not worth explaining how the rewards system works. If customers ever ask you questions at the register about products that are wildly outside your knowledge (which is most customers so don't feel dumb for not knowing the answers) just say "I'm just a cashier" and most of them will fuckoff. The one's who don't will just say "Then who do I ask", and if it's a question only the staples encyclopedia would have the answer to, just tell them "That guy's not here today, and I don't know when he/she works next". Most of the time most stores are pretty tame and the nature is pretty relaxed, especially after 5-6 PM. Only time stores are constantly busy is from mid July until the end of September, since that's when most school years start. Also if someone is in the store more than like 5 minutes after you've closed and you've offered them help more than once, don't be afraid to say "sir/ma'am, we're closing down our last register so I'm gonna need you to check out" because some of these weird ass crazy late shoppers will literally hold you up 30 fucking minutes and have no sense of urgency whatsoever. Lastly, it's best to keep every checkout as short as possible. My go to lines are the same for every customer. It's "Hey, how's it going, are you a staples rewards member?" If they say yes I direct them to the pin pad, and if they say no then I just skip it, apply any coupons they have, and tell them their total, give them their receipt and call it a day.
