To add to what others said here, another salient factor is that in Taiwan it's pretty possible to get late night food, drink, and other things. These things are almost non-existent in the US which would make working night shifts extra rough.

Depends on where the fab is. I agree if we're talking about rural Arizona, but if the demand is there, I guarantee you that someone will open a franchise (or six) down the street and operate overnight to meet that demand. In and around larger cities though, it's not really a problem. There is usually _something_ open, even if it might not be a long list.

apart from NYC (and maybe Las Vegas), I don't know any other US cities that has functioning food places that operate throughout the night abuduntly

do you have examples?
