Wingstop

I was in the Wingstop in Rialto CA on October 22, 2019 and the employee didn't have a name badge on and she was rude she didn't want to give me my refund back and tried to cheat me on my money I paid 22$ she slammed the money and didn't give me the right amount she started calling me names and called me a lil boy! I spend a lot of money here I deserve respect! What company don't allow their employees to wear name badges? Also she said she would do something to my food if I order there again I am outraged by this I will never order from wing stop again
