Food*****s closes early than the actual time on their website

I got to food*****s market in Harvest Place at 18:55 the door was closed, but on their website it says they close at 19:00 I asked if I can get in the security guard said the store is closed I said but there's ample 5 minutes left, I only need one item from the store and they had customers inside shopping they denied me access and some lady was busy saying "she's busy fighting can't she see the store is closed"
