Drive Through doesnt give full order

The people at the drive through keeps forgetting side orders or burgers. <br> <br> Happened twice so far. <br> <br> Most recent event about a week back before i left down to durban , order some hot wings with 2 love me tender burgers, lucky i parked outside with the girlfriend as it was a late supper , only to find out they gave us one burger short. <br> <br> As i walked in to ask for my order i met 2 other couples that also received short orders. only for the lady behind the counter to tell me that she forgot. <br> <br> Last time i ordered 4 boxes of 24 piece wings only to realized one whole box was short! 1st time was my fault for not checking which makes no sense you
