I went to Als today for the first time as i needed a new regulator and hose to replace mine that are broken and no longer made, so i have no idea what i need since everything is so new, so i ask the guy "im looking for a regulator..." and thats when i was cut off and told behind you and down the isle, so i thought well, maybe i can figure this out and of course i couldn't so i went back and showed him a picture of what i have for a regulator, he quickly says that i need a dual regulator, which i dont because i put my tank away after i leave so the cows dont damage it and i only switch tanks once a year and dont keep 2 tanks full at a time.. he wasn't listening and he sent me back down the isle by myself to look stupid, so I did for a few minutes and pretending I knew what I was doing.. Thats when i left this store with 3 unwilling to help employees and i was the only customer there at 2:30 in the afternoon. They just lost customer and thousands of dollars. How aweful! Avoid at all costs! Drive to mesa!
