I was walking towards a machine in the gym, I wanted to work on. There's this cute girl sitting on it while she was waiting for one of the squat racks. I asked her if she was using the machine, she replied with a "No, you can use it, was just getting it warmed up for you". I just smiled and carried on with my workout. What could have been a witty reply?

One I can think of is "that's sweet of you, pretty sure I'm gonna hit some PRs now""
