You may get along with a lot of people and you may even go out with a lot of attractive looking people. However, people can be gorgeous as hell, but you still may not be a good match with them. Some people may have a great personality, but you can't imagine ever kissing them. You might find a really great guy or girl and you like almost everything about them. In other words, even if they seem like a good match, they might not be the best possible match for you.
I always suggest that you have certain forms of communication before going on an actual first date with someone that you meet online. Those communications are either emails or text messages back and forth, at least one phone conversation, and sending each other a few pictures. You can even add each other on social media, if you're both comfortable. So if you've gone about preparing for a first date like I suggested, then a person not looking like they said or had shown online, wouldn't be one of the deal breakers on a first date.
I'm saying chemistry and not attraction, because when there's the right kind of chemistry, there is attraction. When there is good chemistry, a healthy foundation can grow. A relationship should be based on a healthy foundation or it won't last. When you have good chemistry with someone, everything else naturally happens, including physical attraction. Yes, physical attraction can develop with great chemistry.
If a person isn't kind to waiters, etc., it shows lack of respect and love for other human beings. It shows that they feel superior and are on some type of power trip. This is a big deal and this person truly needs to get over themselves! If a person acts like they're better than everyone else, they get two red flags. See below.
Well, here it is folks! The exact opposite of one of the most beautiful qualities (being humble). As sexy as a confident man or woman is, when a person is arrogant it's so damn ugly! An arrogant person loves to hear himself talk and thinks he's always right. They try to dominate conversations and like having the last word. The men are usually alpha males. The women are usually snobs. They boast about themselves and their achievements in a way that they portray themselves to be deserving. They usually look for perfection (which doesn't exist) in a partner. An arrogant person feels the need to overcompensate where he's lacking.
