I'm a cashier and never think "oh they're only buying one steak. they must be eating alone."

Why would it be sad to eat alone?

Live for yourself.

Why do people think that there is something wrong with being single?

This is sad! I do the same thing ;)

you have some serious self-esteem issues. You may want to seek help.

I highly doubt the cashier would really notice or care about whether you buy one pork chop or two, and you shouldn't be ashamed of eating alone anyway. There is nothing wrong with that.

I used to work as a cashier in a grocery store and all I thought about as I rang everything up were the produce codes and how I should bag things, whether I should put lighter items aside as I rang them up if I saw heavier items further down the belt. I can assure you that whether people got a small amount of food or a large amount of food, I never thought anything about it one way or the other.

Most cashiers do not care.

Why would anyone care if you eat by yourself or not .. You clearly have issues in that area, find something else to focus on instead of your lack of partnership.
