Mcdonald's India — Coke is being provided in unwashed plastic glasses

Address:

1st Floor, Kukke Plaza, Akshayanagar, Bengaluru, Karnataka 560068

I went to mc donald’c 1st Floor, Kukke Plaza, Akshayanagar, Bengaluru, Karnataka 560068, there i found that when they have the coke to me in plastic glasses i have seen a white layer of wax/ oils and i showed to the employee as well then she said ok i will give you in another plastic glass. When she provided in another glass i have seen same whitish layer and showed to her as well, then she called their manager and i showed tohim as well. Then i said why you are not providing coke in dispostable mcdonald glasses. He said those glasses are just for take away customers. Then i requested them to provide coke in disposable glasses and they did same. Then i showed to both of them and said now that layer is not visible may be your glasses are not washed properly.

This is not good. We trust and go to branded restaurants so that we can get good quality hygienic food but if they provide their food and beverages in unwashed glasses than that it not hot. Please analyse it and try to fix asap.
