Just to state for record's sake, I don't go to the gym to:
1) Dress in the latest sports attire and model for everyone
2) Flirt with the women
3) Talk to everybody instead of working out
With that being said, I do go to the gym because I want to stay in good physical condition while eating whatever I please and I want to get stronger than I already am. The keywords there are "stronger than I already am". This means that I have limits and weaknesses that I'm trying to overcome, but I can only do that by pushing myself to those limits.
Just to make sense of this, when I ask someone for a spot in the gym, I am asking for someone to assist me. If I am on the bench press, that may mean "breaking" the weight by removing it from the bar, and then watching me to make sure that I don't let the bar loaded with weight crush my chest. That's it! I don't ask for a spot so the person can do the exact opposite of what I do and can get a workout in too.
When I'm on the bench press, I don't want the person spotting me to pull the bar up as I'm trying to push it up. Why? Because if someone else is pulling all the weight, what kind of workout am I getting and if someone else is doing all the work, then I'm not getting any stronger.
You may or may not be into fitness, but I hope this point hits home for you...if someone else is doing all the work for you or taking the "weight" of the world off your shoulders, then not only are you living a sheltered life, but you're also not getting stronger. So when that "spotter" or that "yes" man isn't around anymore, an actual problem will crush your weak self. Just remember that it's always good to ask for assistance, but never ask for a crutch.
