Opinions please, I'll appreciate some views on this issue, thanks everyone!?

Alright. This is Kuwait a developed country, now the gym I go to Oxygen is a private gym I have been a member there for 2 years on and off traveling and coming.. recently the manager complained about me sweating alot, so I brought two towels to do my best to clean the tredmill, today he told the reception, do not renew his membership because I wore shorts, he says I sweat alot and the machine will be damaged.. lol I thought it's funny, its a great experience for me... I run 2 hours on the machine, daily.. I sweat ALOT I admit but I believe in being having positive and hard working clients in the gym, but this guy seems no managerial skills.. I took it personal for few minutes but then said hey? There's so many gyms in the world! why am I sad about this? lol
