Shady, very rude, rip-off artists. Have been taking my 20 lb propane bottle there to get it refilled because they are close to my house. They have always been rude. Started to notice the propane didn't last as long, so I emptied it all the way and weighed it before and after they filled it. Only got 16 lbs from them. Next time I politely informed them that it had been underfilled the last time. The man laughed at me and then only put in 13 lbs. Just took my bottle to Wyandotte Welding and they gave me a full 20 lbs and charged me $5 less.
