Wrong operating times displayed

We go to Spar in Zewenwacht Mall and see it is very full. I check the operating times sign clearly displayed on both sides of the door and see that they close at 9PM, so we decide to first go eat something and come back. When we returned at just after 8, we see that they are closing and won’t let us in. I have no problem with them closing at 8PM, but please change the signs outside you door!
