I visit the Big C Mall regularly and the toilets are kept as clean as they can be,the cleaners are always in them cleaning. You are obsessed about the food, I remember your rant slagging off the type of people who used it, it’s always busy, foreigners and Thais so it can’t be that bad. Not everyone can afford steak dinners, stop being so judgmental and if you don’t like what you see don’t visit the place and go back home to whatever country you come from and see what’s that like.
