I'm with you there tatty. The ones that get me are the texting faggots and at my gym that is a literal as well as figurative statement. They get on a piece of equipment, starting texting for 2-4 minutes, do five reps, do 2-4 more minutes of texting, etc. I've seen some people spend 20 minutes on a single piece of equipment and maybe do 20 reps total. I usually go up to them to ask if they are nearly done if I want to use that equipment. Almost all of them either finish up or scurry away like a cockroach. I don't take my phone on to the floor of the gym. It stays in the locker.
