Friends with bad manners.

I have a big group of friends and we always hangout. We've been chatting on discord for a while and one of my friends wants to hang out. I was excited and said yes so got the whole time we were riding in the car and talking. We stop at a sit down restaurant and go inside, I have realized I'm the only one talking in the friend group for many reasons. One of the biggest reason is manners, which they have none of. They will look at the waitress awkwardly and say what they want without a please or thank you. I on the other hand gladly use my manners as I work a job that requires having politeness, I also just enjoy talking to people in general. One more thing is that I hate when I have rude costumers or have people that intentionally ignore me. I don't have a problem with people who dont talk and maybe shy but I may just have high expectations.

Anyway my friend and I sit down and the waitress comes, I say hello and ask how they are doing. My friend looks really annoyed and orders very quietly and rolled her eyes when is asked to repeat. I get annoyed as well but blew her off and waited for our food. We eat and I throw in a tip and we go.

I had to be home at a certain time and I had a gift for my friend so I asked her to come inside for a moment. I introduce her to my dad and he says hello and she mumbled and looks away. My dad looks at me and I shrug not knowing what to say, he just walks away without a word. I understand some people just don't like talking and that's okay! My problem is just not using manners and it is a big issue for me. My parents had brought me up on using manners and always being nice to people. My parents had told me that I have a problem with getting bad friends who end up taking advantage of me which has happened a lot in the past.

I say goodbye after giving her my gift and she leaves. I don't like being angry at people for not using manners but I really can't help it. The friend in question works at grocery store and she is told by several managers to start saying hello and using her manners which she has ignored or gotten aggressive over. I can't help but feel that every friend I have made is either rude or extremely dismissive of me and who I am. I want to make friends but I always make the wrong ones and I don't know how to stop it. I also think I may be unreasonable for having the expectation of using manners in places as well. But I don't know, any help and advice is greatly appreciated. Thank you!
