hi, adorning wounds. i'm gay. this is a very awkward situation. it sounds like you are not out at work at all. so, coming out to someone at work - someone you also have a crush on - must be very scary. other than this person being friendly, are there any other signs they might be gay, e.g., from how they dress or talk? striking up a conversation to get to know them a little better is an option. asking them what they do for fun or where they hang out after work might give you some insight into their sexual orientation and would not give your orientation away either. honestly, i have had situations were straight men were friendly to me as a trap for me to hit on them. in one instance, the guy thought that just by answering his questions and being friendly in return by making small talk, that i had set my sexual sights on him. i thought i was involved in just friendly, non-sexual chit-chat initiated by someone else.

also, bear in mind that as a salesperson, it is his job to be friendly and get to know repeat customers. does he approach all customers like he does you or are you alone is being approached by him? if his approach is the same to all customers then it appears he is just conducting business as usual.

still, quite frankly, i believe it is usually safest NOT to date people at work. i have been appalled at the evil, untrue rumors that homophobes have spread about me when i was attending college and in the workplace. and, people believed them. it's best to meet love interests in gay establishments where one has friends who can introduce you to potential romantic interests. and, that is what i suggest that you do if you are concerned about your safety and keeping your job. good luck to you!
