I work closing shifts and at reg customers often ask what time I get out of work. 99% of the time it's a completely innocent question from people who work standard 9-5 jobs and are just getting off work themselves. I am starting to get nervous that this will open me up to some unsafe weirdos, especially since we get out so late at night. Does anyone have any good lines/tips to not directly answer that question but in a customer servicy way?
Edit: thank you all for the responses and the tips!
