Wendy's Old Fashioned Hamburgers 4

My family and I go to Wendy's often. Today we went to one in
League City Texas and the cashier had a horrible attitude.
She had mixed up our drinks and she had left the register and
gone into the back........I assume it was the manager telling her
that she had to stay at the register and the attitude again......
speaking in Spanish and rude..........no smile or thank you to be found!
She was having a bad day but she sure wasn't helping any making anyone
else's day nice.
Very rude!
