Wierdos in the gym

All of us who go to these gyms (regularly or irregularly) wouldnt have missed several strange categories of people in there:
1. The struggling amateur- This is the guy who has just joined the gym but is clearly not cut out for it. He spends more time drinking water and walking around the gym than working out. When he works out , he typically gets the angles and body postures wrong.
2. The irritating floor trainer/s- The personal trainers are typically good but the floor trainers are a massive pain. The funniest thing I find about them is that Trainer No.1 may come and say that "Adjust your seat to position.4" . You would do so and continue exercising and then suddenly, Trainer No.2 will come & say "Too high- reduce to positon.3" . Damn bugging , especially for the struggling amateur.
3. The noisy muscleman- These are those Salman Khan varieties. Every gym needs them to be authentic. But , the loud grunt while lifting some 150 kilos is just unbearable and not done.
4. The treadmill hunters- 70% of the people come to the gym to just run up and down on the treadmill (i have never understood why). Typically, in a city like Mumbai, the treadmillls are always occupied. So- you have these guys who come up to you and ask you - "Aur kitna time??"
5. The pushy Mumbai local train types- These are two types of these:
i. Chappies who do an exercise and then leave their towel on the equipment. The towel indicates that they are gonna come back soon and that the equipment is "reserved" for them
ii. Folks who wanna finish off their routines first and so, will literally stand on your head whilst you are exercising to ensure that they can go next.
6. The sleeper abs- These guys get onto the abs trainer at the end of their routine. They are typically very tired, but to reduce that fat paunch, tend to (try &) do a lot of crunches. And invariably they lie down on the equipment and take "v long" breaks with their eyes closed between their sets.
Are they more? Maybe, the dainty lady , the elderly gentleman and so on...But the above were the top 6 that came to my mind. Happy gymming.
