Yes, actually it's happened to me several times. And I just looked at my most recent confirmation at BCV, where I requested "upper floor" (I thought) and it says "request top floor". But I don't think it's unique to BCV. We recently made reservations at OKW, where I also requested upper floor, and that reservation paper says "request top floor". I just figured they only had a button for "top floor" request, not "upper floor". BTW, with all these "top floor" requests, I've never gotten top floor at BCV, only 3rd or 4th.
