I am a small business owner, but my work is project based and a one time thing for most clients. From the other side as a customer, I’ve stopped going to a business when they commented about not seeing me for a while. It’s one thing to say ‘hey, it’s great to see you again, how’s everything going with (insert earlier project/service)’ and another thing to say ‘you haven’t been here in a while, you should come in more often.’
