I think it's common to stall when you are making a large purchase. The money that you have means a lot more when you don't have much and you spent a lot of work to get there. It makes me wonder because those rich people can spend so much money and not blink an eye.
Rich people who are from humble beginning do not really spend that crazily unless something has psychologyically gone wrong somewhere. The guy I talked about in the reality show was a multi millionaire in dollars. People probably don't get richer than that though, and the guy still stalled.
