Disgusting Smell

I regularly visit the Mugg and Bean in Canal Walk and today 17 June I planned on relaxing with a cup of coffee before the work rush of tomorrow. I was planning to buying something at the counter for take aways when I got this terrible sewage smell. The cashier was acting as if she wasn't smelling it but then when we asked what it was she was embarrased to say that they were cleaning the drains. The mall was full and the restaurant was full too for them to clean the drains at that time. The smell was so bad that if put me completely off from getting anything and coming back in the future. The drain that was being cleaned was right next to the work station which made it even worse. They should really take not as to when they have their drains cleaned as that just put me and my family off from ordering anything from them in the future.
