This Dollar Tree cashier is an absolute pro, as he owns a Karen and her husband all while keeping the checkout line moving.

This guy isn't taking any crap, and he is prepared to throw profanities right back at anyone who chooses to confront him. This Karen is trying to get a refund for old items, something he informs her is against store policy. Then, she tries to get away with paying less for her new items. "You're a broke b**ch," he tells her. "You got $40 worth of s**t in a basket and you're sitting here counting." After getting offended by that statement, the Karen informs him that her husband has a grand in the car, and she goes to get him. "You've got Walmart boots," he tells the husband.

While the chaos unfolds, he doesn't miss a scan in the checkout line, and customers keep rolling through like everything is normal. Just another day at your local Dollar Tree.
