Catcuddler - I disagree.
Gay men are often overtly physically affectionate with female friends, and acquaintances, because they are 'safe', so no barriers are being encroached.
Therefore, if this man may be gay, he may be behaving as he does with other female acquaintances, which explains his behaviour.
That said, no man, or woman whatever their orientation, should assume that because no discomfort is intended, does not always automatically mean that it is not felt.
If the poster is uncomfortable, she should make that known, and if the behaviour persists, she should either report it to the manager or owner, or take her business elsewhere, or both.
