BP Waterloo service standards

I visited the BP service station at Waterloo Verulam on Friday 29th November hoping to buy a bunny chow . I noticed a Black Friday special advertised on the store display at the area were you place your orders for the items you wish to purchase. I was hoping to purchase the Black Friday bunny chow special only to informed that although I was in the store I needed to order online. The food was ready to be despatched visible on the counter but was told but the staff on duty that I needed to go online to purchase an something that was readily available and I was already in the store . They then checked with the manager on duty who informed me that he still further needed to check with someone else . I don't understand. I am a customer wanting to purchase in the store which I drove approximately 7 kilometers to get to only to be told that I must order online. Pathetic service.. I will definitely not recommend this establishment to anyone again. Simy I was there to purchase but was given the run around for something that was not a special request but rather readily available. Very very very bad service by the manager who let a customer walk out the door without even making a suggestion. Useless and good for nothing
