I have been a cashier at a convenience store before.
You serve everyone as long as their behavior and manner is okay.
There are a few exceptions.
Someone who is too intoxicated or someone who is belligerent to either the cashier or the other customers.
If someone has an insulting attitude you can refuse to sell to them. You can simply pull the goods they plan to buy and set them behind the counter and ask them to leave. If they do not like it they can take it up with the manger. If they persist you call 911.
The manager will usually almost always side with the cashier.
They have so much business they do not care is one irritable customer takes their business elsewhere. It is not like when I worked at Sears and every single customer was a valued commodity.
The rules I think have changed at Sears but when I worked there if you got a customer angry with you, they could go home rip up their dishwasher, washer and drier and every other major appliance and bring it to Sears and ask for their money back, and Sears would comply.
The prerequisite was never, how are your relations with your wife, or, which religion do you follow? Are you gay?
If you had the credit we ran your credit card and the power of the all mighty (plastic) dollar prevailed.
People often came into Sears and bought many washers and driers at a time because they were contractors and needed them for several units. No questions were asked about their marital status or if they liked to dress in drag occasionally.
My point is you can see both sides of the equation. In the convenience store where they only care about fast courteous and continuous orderly clientele.
And other services like Sears (at least the ways Sears used to be) where customers are serviced in many areas.
Yet still these areas are the same regardless of marital status.
LGBT people need shoes and clothes, they need to clothe their families too. They need washers and driers. They get married and buy houses, they need lawn mowers and to have their automotive repairs done too.
They need photography memorabilia and to get their hair cut.
Then there was the time when I worked in a restaurant as a short order cook. I was being trained on how to serve side dishes to the public.
I asked the chef how many peas to put in the side dish?
The chef replied, "So it is reasonably full.".
The dish is not too full and not so scant that you can count every single pea.
This is the kind of service LGBT (all) people expect whether it is at a convenience store, Sears or a restaurant, reasonable service, reasonably full...
