One of the most annoying things a customer can do is to wait until they get to the cashier, according to a former cashier at a major fast-food chain.

Aeria said that customers who don't decide on what they want before it's their turn can be annoying for cashiers.

Staff members notice when you fill up your water cups with soda.

Customers like to try and avoid paying for soft drinks by making free-water-cup requests, but this won't make them friends with the staff. Beverly Friedmann, a content manager who used to work at a major fast-food chain, told Insider that you will likely be asked to pay for your drink if we see you.

Workers don't always have time to call out those who sneak soda into their cups. Friedmann said that if the store is busy and staff members are not able to confront you, they are judging you.

It is considered rude to use the bathroom without buying something.

The staff will start to notice if you slip into a fast-food restauran just to use the bathroom.

It is one thing to have an emergency, but it is another to use the bathroom without purchasing something when paying customers are waiting longer than they should have to.

Friedmann told Insider that if you occasionally buy something small or donate your spare change to charity, workers might appreciate it.

Asking for tons of condiments or utensils can be frustrating for workers, especially if you just stocking up on them for personal use.

It is not a crime to ask for a few extra packets of your favorite sauce, but there is a fine line between finishing your meal and stocking your kitchen with condiments.

The supplies and condiments are supposed to be for a single meal, Friedmann told Insider.

She said it could be annoying if a person stuffs bags with more condiments and extras than they need for one meal, as the workers have the responsibility to replenish containers inside the store.

Allowing your children to order their own meals may feel like a good way to foster their independence, but dealing with indecisive or confused kids can be frustrating.

I can empathise with wanting your kids to choose their meal and get something they like, but if they are too shy or don't know, just order for them.

If you can help your kid select what they want ahead of time, you can allow them to order for themselves if there isn't a line.

The entire kitchen can be slowed down by making very specific order requests.

Some workers don't like ordering fast food when customers make very specific requests.

Customers making weird requests for their food is one of the most annoying parts of working in the fast-food industry.

Simple requests, such as not adding ice to drinks or skipping lettuce on burgers, are usually no problem, but Aeria said that adding other toppings or asking for your food to be cooked in a certain way could be a huge headaches for staff and might result in your order being incorrect.

People leave a mess after eating in a restaurant.

Fast food may be the ultimate type of casual dining, but that doesn't mean you should leave your table manners at home.

Aeria said it was annoying when customers didn't clean up after themselves and left their food on the table.

Aeria told Insider that it is courteous for customers to throw away their own trash since it gives workers more time to clean up and provide a better environment for everyone.

Since they are likely not the reason your order is taking longer to prepare than you would prefer, being impatient or rude with staff members is not cool.

In any establishment, staff members should be treated with courtesy and respect.Shutterstock
