Vincent McDonald's put to shame

We went to the McDonald's in Vincent to go have lunch with the family. We ordered for 2 kids and 1 adult as the special they have that one can order with the cell phone app had to be done separately. I wanted to order 6 of the one special, but was told that we have to do the ordered separately and swipe a card for each order, which I thought was ridiculous as it was for 1 family. The manager couldn't even understand that it was for one family and we didn't want to swipe our card for each transaction. We want to swipe once for all 6 burger special. They had 2 of the ordering stations, but do not understand why they were not switched on when they were open for business.
