Everyone deserves some common things from a relationship: love, trust, respect, etc.

Other expectations may very well be reasonable, but others might be totally unrealistic.

For example - I may think I deserve someone rich, fit, and willing to support me so I can be a housewife. Is that realistic? Definitely not. I don't deserve those things, they are just fantasies (not my actual fantasies btw, being a housewife makes me cringe!). If I was to hold on to my fantasies, whatever they are, then I am going to miss out on a lot or possibly all opportunities which might lead to me being happier than I could believe.

You really have to look at your desires with a critical eye. It isn't settling on someone to not have them meet all your dream criteria. My dream guy? Totally unrealistic for me to hold out for him. But some aspects are valid things I expect - for example, I wouldn't get involved with someone who was terrible with their money, or who wasn't a hard worker. I don't expect them to be rich, but I also know that I am not willing to completely support someone else financially. I work hard and have good management skills. I also would not get involved with someone extremely religious as I am an atheist - unless he had zero intentions of trying to convert me. Same with someone sexist or racist - I completely disagree with those belief systems and would not remain with someone who was either.

As to the girl at the counter - I wouldn't have gone up and interrupted someone's conversation just to say hi either. I see people I know and like and yet respect their interactions with others. I think it was respectful of you to just go past.
