unhygienic and disgusting

I was recently at Spur in greenstone and at the table next to me I witnessed a child using a bottle of tomato sauce and after pouring it on his food he licked the bottle - he did this atleast twice during his meal. i went to the manager and reported what i had seen and how unhygienic this is and why do they put bottles on the table not squeeze bottles or sachets and all the manager could say to me is he sees this alot this is completely unnacceptable and disgusting
