I have been a victim of racism at a Sainsbury's supermarket when they refused to sell to me an energy drink and they demanded that I go under additional checks than British people to prove I am older than 16 years old when I am 30. I witnessed 18 year olds British people buying energy drinks, in front of me without being challenged to show their I.D.. The problem was one particular staff that demanded to see my passport to sell anything despite there was NO SIGN "CHALLENGE 25" ON ANY OF THE ENERGY DRINK SECTIONS. I didn't know that you now have IMMIGRATION CONTROL DUTIES AND SECRET AGENTS IN STORE. When I raised my concerns with the manager on duty showing evidence about everything I stated, I was treated like a criminal having guards approaching in an attempt to intimidate me despite I was calm. In the midst of this chaos, an African young lady approached me showing support about what was happening, understanding I have been a victim of Racism. I contacted Sainsbury's through every means possible, more than 7-8 times and they keep on ignoring me. Do you really think I am not going to stand up for my human rights? For Goodness' sake, I have evidence for everything I am saying and if you keep on supporting your staff's racist tendencies and misleading customers, the WHOLE UK needs to know.
