Takes Me Higher Puns

I was once staying at a hotel which had two lifts, one for the bottom half and one for the top. I was intrigued with the system and asked the manager about it, his response was a fairly terse one "no funny business here, take the lift like anyone else would" he said strictly.

During my stay I needed to get to the higher section of the building, leading me to use the top lift. However when I came to move it, it took quite the effort and persuasion to get it to shift. Once I'd fiddled around and pushed a few more buttons it slowly made it's way up.

It was at this point I realised the manager simply had a stiff upper lift.
