Health risk

I went to The mr price at wonderboom junction in Pretoria on Saturday , as i was standing looking at the funky water bottles they have thinking if i should buy one a little girl took a bottle and put it in her mouth as if she was drinking out of the bottle , she then walked around in the store with the bottle in her mouth the whole time, when her parents was done at the till her dad took the bottle out her mouth and just put it back on the rack.I then picked up the bottle and gave it to one of the ladies working at the mr price and told her a little girl had the bottle in her mouth , she took the bottle from me said nothing turn around and just put the bottle back on the rack.I was shocked !!!! it is a health risk or does Mr price not give a ****m ?? i looked at her and said really you going to put that bottle back so that someone can buy it and not knowing that bottle was in someones mouth she then just looked at me picked the bottle up and walked away not saying anything again....i dont even know if she went a put the bottle back after i left the store.i will never buy a bottle from Mr price because it is super clear Mr price staff does not give a **** about any health risk to their clients.it is just as well i go to a pie shop some licks the pie and the store puts it back to sell to a client.
