Jalapeño sauce out of stock.

one weeks back, I went toc Mc Donald's the one In Boksburg, Parkdene, to buy Nuggets and i was told the Jalapeño sauce was out of stock, and they offered the chilli sauce,I went again today to order nuggets. I was told that the jalapeños sauce was out of stock again, funny enough I decided to order online and the sauce was available at the same Mc Donald's. I don't know if they are trying to force us to order the BBQ sauce or what. this Mind due this is the only Mc Donald's I've ever experienced this at.
