expired food and disgusting service

Went in the store to buy a sandwich and I noticed expiry date was 28th which was yesterday. So I spoke to lady working in the kitchen who was busy making the food and she responds by saying that no new sandwiches were made today so please buy what's on the shelf . I looked at other sandwiches with pack date of 26TH and sell date by 28th . I confronted the black lady again working and asked how can this be sold in your shop . an Indian guy arrives and says that the sandwiches are fresh and made today . reason why it's In that package with expiry date is because the package was re used . I said this lady just told me nothing was made today . His response was that she doesn't know . She came to work late . I'm disgusted . Il never shop at that food *****s and i think the food inspectors need to pay that place a visit... how unprofessional for clearly lying and utter ********.
