I think there is a stigma attached to working in McDonalds. I remember teachers saying to us about 'ending up flipping burgers' if we didnt get decent exam results. In a time when jobs were a plenty working in McDonalds was seen as rock bottom.
The foreigners though dont give a shit, they'll do anything, and work their socks off. I've got a mate with a cafe, his biggest concern is that asians or foreigners will set up close by as unlike him they are prepared to open 24 hrs a day!
