Not sure if this is the right place for this. If not, mods please move it.
Anyway, I've been going to a gym to work out for a few weeks now, and one of the girls that works the front desk (who also happens to be a personal trainer) seems to be going out of her way to say hi to me as I enter/leave. Now, I know generally this is not an ioi, but she's been fairly consistently stopping whatever she's doing, or interrupting herself talking to someone else in order to say something to me.
Is there any solid way to try to move it along and tell if it's a true IOI or just my imagination?
