Britt McHenry -- Tow Truck Company Fires Back ... 'It's Your Own Damn Fault'

The woman on the receiving end of Britt McHenry's impound lot tirade is praised by her bosses -- who say they're PROUD of the way the employee kept her cool amid the ESPN reporter's attacks.

As we previously reported, McHenry exploded on the impound lot attendant -- calling her an unattractive, uneducated loser. It was nasty evil stuff.

TMZ Sports spoke with the manager of Advanced Towing in Arlington, Virginia who says ... "It's unfortunate that [our employee] had to withstand that."

"It wasn't [our employee's fault] that Britt's car was towed. It's her own fault. She was in the wrong. That's why she was towed."

"Now people can see what really happened. Sometimes you have to own up to your own actions."

As for the employee, the manager says -- "She's the kind of person we try to employ here. She handled this the right way. She kept her cool the whole time."

Britt has since apologized and ESPN has suspended her for a week.

So, how did the tow company feel about her punishment?
