I work in a quiet residential street and the neighbours opposite are retired so especially in the summer are in their front garden pottering around, I am just as discreet as I can be, I don't see loads of clients daily, ask them to park round the corner, I also always say hi if they catch my eye, small talk about gardening, which I know fuck all about! Difference is I don't live there.
I get paranoid that they suspect but don't think they do x
