Not Sears specificly, but retail in general can be...interesting.
Assuming you'll be a cashier, you will see ALL kinds of people. Most will be more or less normal. But you'll get a few (at least one or two per night, more durring the holidays) that are either morons, crooks, or crazy.
I used to work at Target. I'd get people trying to play the system, trying to comit fraud, mistakenly try to return merchandise that we didn't carry (you'd think the K-Mart tag would be the first clue that they DIDN'T buy it a Target!) and all sorts of screw-ball behavior. Just smile, politely quote the policy, and if they won't take no for an answer, call for a supervisor.
Then you get the just plan RUDE customers (although I didn't get too many myself) that you want to kill, but always remember "service with a smile!".
Retail is not for the meek.
Also, and again this is generaly speaking, whatever hours you tell them you can be scheduled for will be in effect for about 2 weeks, until someone quits and they assign you their shifts. Pretty soon you are working everything BUT the hours you originaly told them you'd be available for and/or twice the number of hours you requested. You'll need to be firm with them from the begining, if they schedule you outside your normal availability (without asking you first) nip it in the bud right away and tell them to take you off, you are not available those days/hours. The more you let them get away with it, the harder it is to get them to stop.
Otherwise, good luck!
