Interesting cultural question

For those of you either outside Israel, or have recently arrived, please comment on the following:
What is considered a lot of money?
Is $5 a lot of money?
Or is the limit $10?
How about $20 bucks? Is that a lot? Or maybe the limit is higher?

Another question – how much is a pint of beer at your neighborhood bar? How much do you tip for just one drink?

Looking for some data to evaluate. Your responses are greatly appreciated.
