A customer came to apply for a house and seemed like he was interested in me. He asked my name, then told me his as he left. He came back the next day and asked me who would help him with his housing application as I was going somewhere else. I came back to cover for a colleague so when we were alone he asked 'how have you been?' even though it had only been a day since I saw him and he randomly said 'he was sorting himself out' - I think he was referring to his housing and job situation. When he left, he ignored my colleague and he looked at me and went. Was he interested? I did fancy him but felt I couldn't act upon it being at work. I don't know if I should have been more receptive or left it.
