Do you hate it when you open a door for someone and they don’t say thank you?

I was walking to a sandwich place for my lunch break and there was two girls behind me so I opened the door for them and they walked in without even saying thank you or looking at me.
I know you might be thinking that I am just whining or something but I not only opened the door for them but also gave them my place in line in front of me because if I just walked in and not opened it for them, they would’ve been behind me. I don't know. Am I overreacting? Should I still be a gentleman?
