Young Becky is, alas, a shining (?) example of the service in the catering industry in these parts. Jobs are difficult to come by in a rural community and the local pub or restaurant is often the only possibility for young people who can't yet drive. As a result, these businesses are full of youngsters who don't really want to be there but need the money.
It's also worth noting that most of these tweets are during the day. Lunchtime or not long after so it's possible he's stopping to eat whilst out shopping or looking round his new neighbourhood.
