~ I have half an hour another country and the same thing happened to me as to you, I saw and entered the casinos, I saw how people moved their money, and they gambled large sums, actually I was embarrassed to bet very little with respect to them, I didn't want to be the one to make them laugh at them, and so I refrained because I really didn't think I was at their level even to be able to play, I don't know, I think I felt a little bad, maybe intimidated.
Interesting experience. I think it's good that you didn't try to "be on their level" and bet big amounts in order to get their respect. I actually can relate to your story. I'm almost always betting very small money, like $0.10 or $0.20, and sometimes I have exactly this feeling of embarrassment you mentioned, when I post about me winning $15 with 150x of my bet win, while other people would bet $10 instead of 10 cents, and win $1,500 with the same luck. But I try to banish feeling of embarrassment because I know, there's no shame in not being rich.
