For people buying stuff:
1) When in line to make your purchase, have your sh*t together
before you get up to the cashier. Saves everyone time and headaches.
2) Don't use the cashier as your information desk. This is especially true if the line is twelve-deep behind you and said store has a specific area for helping you find stuff.
3) Read your coupons before trying to use them. Saves you having to argue later when the cashier can't apply it to your order.
4) Store staff are not your babysitters. If you can't keep your kids under control, you shouldn't expect some minimum-wage making sales clerk to do it for you as you're trying to make your purchase.
5) Read the signs around you so you know where the line starts, if there are any restrictions or special conditions going on, etc.
For people selling stuff:
1) If you've got a line starting to form, you might want to get extra cashiers
sooner rather than later. Lines encourage people to get their stuff faster... making longer lines...
2) If some idiot gets to the cashier and still isn't ready to make a purchase
and there's a line behind said idiot, send said challenged soul to someone who can help. If your store isn't situated to handle that basic workflow, they probably need to look at their processes.
3) Clearly label where the line starts and stuff like that. Keep it simple and use big print.
4) For God's sake, if you have people wandering the floor doing whatever and there's a huge line of people waiting to buy stuff,
get some more cashiers working! Is it that hard to figure out? Seriously? You
want their money! There's a recession on!
*exhales*
Aah. I feel better now.
And I'm very grateful I don't work retail anymore.
