Gelmar will not see me again

I went on Friday the 3rd of February 2023 to buy some *****s for a project. I arrive there at 16h01 and the person at the door screamed at me to tell me they are closed and that the cashiers are closed and when I looked in there was still customers at the till paying.she said to me can I not read on the door that they are closed. Will never ever buy there again and will also tell my friends of it.
