Out of stock on most meals advertised - Hluhluwe KZN

Today 29/12/2017 I decided to go to our local Steers for some yummy burgers and their famous chips. So I get to the counter to place my order with the Steers employee, whom may I add is also rude and would do everything else except taking my full order. So I order 1 Bratpack - her reply: Oh we out of all small burgers we only have the normal size we are OUT OF STOCK, then I want to order the Sharing 1 option - her reply: Oh we don't have any we are OUT OF STOCK. So then I ask ok can I order 1 Large Cheesy chips and 1 large regular chips - her reply: We only have 1 regular chips left cause we OUT OF STOCK. By this time my daughter is begging for an ice cream so I ask... and yes you guessed it... OUT OF STOCK. So please can someone tell me how a place like Steers plan for the busy festive season? As the manager at said Hluhluwe Steers (Faith) said that they were not prepared for this busy time and then that they ordered Rib putties but the supplier did not deliver. Which is fine but how are you out of chips? Out of ice cream? Out of any and all Real deal burgers? I am very disappointed cause it is like false advertising and if you can't supply why are your doors open? And the staff could really use some basic customer service training.
