When a noun is actually a verb

I swear that on AirBnb’s mobile app. I read that you can get a full refund within 48hrs of your, or the, booking. Meaning 48hrs before.

Unfortunately it appears booking in this case is a verb, meaning 48hrs after my booking.

With a whole team of lawyers at their disposal I doubt AirBnb has made this slip up, and it surely shows that either my level of English comprehension has decreased while in Taiwan for 2 decades, I really do need good glasses, or I was just reading what I wanted to read.

Either way I’m out a booking fee and AirBnb gets to keep my money for 2 weeks, to do with as they see fit.
