I'm annoyed at when you go to a gym, you are forced to buy their gear or they get all pissed about it. I'm not going to name names as that's being a dick but we may know these gyms.
Worst is when I see them doing some seminars and everyone is required to be geared up a certain way. Like look, I go to this gym. Youre here to do a seminar and then you are leaving. I most likely will not see you again in a long time or if ever. I paid for your seminar and now I got to buy your merch to or your pissed? That's BS. This is my gear, its what I want, its what I have already broken in. I got to buy some cheap non broken in gloves because you want me to look a certain way? Nah my man.
Now I totally understand if you go to this gym and are competing, it would be nice for the gym to get its name out there. Like a gi or a gi patch. In that case provide the gear for your athlete. Most of the time that happens. No biggie. But if you are forced to buy a whole other gi because it's not from their Gym then its BS but I doubt it would go down like that. I'm mainly talking seminars here.
