Can’t buy own markdowns or save stuff

So today I was buying the stuff (exceptional barmley apple sausages🤤) I rightfully marked down and my manager told me we’re not allowed which sucks ass. LIKE WHAT ARE THE PERKS TO THIS ROLE IF NOT GETTING FIRST DIBS. Had to leave the sausages as they were the last ones😭😭 now I am sausageless, goodbye my delicious English brekky

Edit: are other supermarkets like this?
