bad service

I am disappointed in McDonald in ALBERTON . I decided to take my family out for supper only to get juice that is diluted and lettuce that is small and brown as if its out of date. I dont understand how the service can be so poor. To think I left a Mcdonalds near me to go to ALBERTON so my children can be happy. When i took the juice back the boy didn't even see the need to taste it he just took it and put it in the fridge and gave me another one. So this means they do this all the time to TAKE AWAY CLIENTS. I am so disappointed and i am hoping this will be taken seriously as i like eating my McDonald's but for now i dont think i wil go anytime soon.
