Don't be at all embarrassed about handing in your CV to shops. I did it last summer and, admittedly, at first it felt a bit strange, but then you realise that they're probably used to it, and they probably did the same thing themselves some time. Anyhoo... supermarkets? McDonalds? How long are you able to work for? Are you going back to school in September? If so, it might be tricky to find something, as in my experience employers want someone who can commit more than just 1.5 months.
