6000 psi nitrogen tank rent , a joke

Went to my local welding supply to get me some welding gloves for my fright harbor cracker box, Just for shits and grins I ask about renting a 6000 PSI nitrogen tank for my motorcycle shop, 250.00 a month and a refill of 125.00 bucks each month if I need it or not.
So a total of 375 a month, And maybe an extra charge if they had to chain the tank up to a wall to keep it secure from falling. She called it a building inspection fee, WTF.
Now I have a sheldon compressor and do not need the Nitrogen, I was just asking.
Sucks living in a oil field boom town.
