Castle light drought not in safe condition to be consumed by clients

I am a customer that visited one of your restaurants today in gauteng Mall of the South. We grew up knowing the Ocean basket as a reputable restaurants offering mouthwatering sea food.While I went to enjoy a meal with my family, I ordered a Castle light drought beverage which I started drinking and enjoying while waiting for my meal.

After receiving my food as I was having the drink my wife asked is it normal what she sees on the drink,as I watched the inside of my glass I couldn't believe it,so I had to call any waiter for clarity as my health was in danger;the waiter gave me an attitude as I was enquiring about the drink and wanted to take if from me but I then told her she musnt attempt to,because I will immediately post this on tweeter and I am aware of food safety within the country.i then proceeded to taking a video of the drink that I had and I was terrified because I have never ever seen such in any drink.This has definitely caused trauma to me and my family as we do not know what would transpire from this.

I need ocean basket to interven in this issue before I can take this on with social media and radio stations because this is highly unacceptable.I spent my hard earned money just to go have filthy drinks at such a reputable restaurant. How many of these incidents have u guys had and were not exposed to the public. I would like clarity on this issue please. I have attached videos and a picture of the bill too.I couldn't even tip the waitress because of the was I was angry. I hope this doesn't turn into some poison in my body because not even the Manager at Ocean Basket Mall of the South came to talk to me about it,we treated like dogs.If this was a white person things would've been different because we don't get same treatment at restaurants.
