I bought my first home recently and hired a company to complete part of the work I couldn't do myself. Met the sales manager very briefly twice to select the product.
He asked for my spare keys on the Friday so they could start early on Monday while I was at work. OK - gave them. Once he called to say the work was complete mid-day on Tuesday, I asked him to put the keys through my letter box before they left.
Instead he said he 'didn't know where he'd be that day' and asked to go to my work. I didn't respond. The next day he put the keys through my door. I made the full payment remotely and confirmed with a screenshot.
On Thursday morning, I received the following text out of the blue. I honestly found it shocking since I'd shown zero romantic interest in him, we'd only discussed the work and he appeared to be significantly older. Also pretty creepy that he had my keys and had hung onto them so he'd have an excuse to see me again.
I just didn't respond, blocked the number and changed my privacy settings. I've decided to do the other work in the house myself.
YABU - It's fine for men to ask you out once the job is complete
YANBU - It's creepy because he had your keys for days, knows where you live and lacks boundaries.
