I think if I had a rude cashier, I'd just want her to apologize and lighten up, I wouldn't demand her job. Cashiers usually come by their bad attitudes honestly: many customers are demanding, spoiled pains in the asses. I've read on JWD before, "Well, it's your job. The customer is the reason you have that job." Yeah, but it's not your job to put up with unneccesary abuse from customers, just because they didn't manage their time or lives well and are in a big hurry. Or just because they're having emotional issues. It's not your fault your store has policies that piss off the customers. It's not your fault that your customers hate to wait in line because we live in a world of instant gratification. It's not your fault that their item didn't scan right and you have to call for help, which takes time.
A little politeness and a smile goes a long way.
Here's a little story from yesterday. I was providing breaks for the demo people. One of my demos involved pulling the wooden sticks out of Healthy Choice fudge bars, cutting the bars into two bite pieces, placing them in cups on a tray. Placing most of the cups in the freezer next to me so they wouldn't melt and keeping the cart, utensils, freezer door and glass clean, etc. It was a day when groups (hoards) of customers would swarm your cart all at once. They'd clean your visible tray of samples, the rotation tray and all of the ones you had in the freezer, making it necessary to catch up and leaving everything covered in drippy, sticky chocolate.
Two girls who looked to be about 16 came and got some samples. Then the girls came again with their mom. Then as mom was walking away, they came back for thirds. I gave them a gentle version of THE LOOK. Then they came back over the fourth time. Giggling. They asked, "can we have more icecream?" I looked at them and said, "Well, yes, you can have more samples. But these will be your fourth samples and you should know that you are making it difficult for me to keep up. But sure, go ahead and have fourths." Then I smiled. They looked a little embarrassed and suddenly aware of their rudeness. They turned and as they walked away, with quickening steps, they said, "Well, we should probably just buy some." And then I didn't see them again.
People come in and boast that they are there for the "free lunch". They come into Costco just to eat, they brag. "Oh no, we don't have a membership, we come in just to eat." I can usually be patient with them. But on a Saturday when you are doing a cooking demo and it's very challenging to keep up and keep your cart and a 12 foot perimeter around your cart clean... It's aggravating to have people with 6 kids come and clean off an entire tray of samples and then brag they only came for lunch. And then they come for seconds and thirds. Its annoying when people refuse to take samples off the current tray and reach over the splash guard to grab from the tray you are preparing. It's annoying when they see 30 people waiting for samples at your cooking demo and they tell you, "Oh yes, we buy these all the time. We have six cases at home." And then they make sure their five kids all have some and they take some for granny who is over in the deli and husband who is over in electronics and Cousin Wilbur who is visiting from the prairie.
But, mostly on Saturdays, people just forget their manners and I am patient with them, while they begin to look like hoards of zombies starving for brains and I imagine calling for back up from the National Guard.
