Bought food but not the full order was there

Hi<br> <br> I bought 2 meals but was given 1 chips short. I went back 2 days later bought 2 mcflurry's told the lady that they must please next time give me my full order as i am not mad but that was my 3rd order that was incorrect. She had the worst attitude and pulle a face at my remark without even apologizing, and said this rude okay. Look if thats your kind of service please let me know and i would then rather move my services to better provider
