Unhappy client

I'm at shopmor in springs came at 16:20pm and I am essential worker, came to buy i've asked to go in wearing my uniform and door keeper tells me I have to follow the line from the back, I asked that what Government said about essential worker's does apply to them, door keeper verbalized yes go at the back, so I went, @16:25pm he decided to shut the doors without communicating with us. I'm so angry right now.
