Personally I find the idea of therapists hugging patients very strange, but I realise some do. Therapy in a coffee shop however, is completely inappropriate IMO. If you are receiving some kind of analytic therapy, the therapy space is an important part of the process - it (should) provide/s a safe, secure place for you to feel and discuss whatever you need to. Boundaries are there for a reason, mainly for your protection but his too. Blurring boundaries and having informal therapy sessions over coffee is only going to fuel the ET fantasies I fear. Can you discuss it in your next session?
