Ridiculous Wait Times - Drive Thru

I went to KFC Florida Road 2 weeks ago to buy a cup ice cream for my baby. I went through to the drive thru and to my surprise it took me 30 minutes to get my ice cream. When I asked why so long, the response I got was that they were short staffed.

I went again on Tuesday the 24th to buy ice cream again and again it took me circa 30 minutes to get my order, this time the excuse was that the system was offline.

Giving them the benefit of the doubt, I went there today again, this time to purchase pops and chips. Today it took me 40 minutes to get my order. I had to hoot and make a noise before movement happened. Today's excuse was that there was a waiting time for chicken.

Surely there has to be a better system to get the drive thru moving. What's the use going through to the drive thru if the wait time is going to be 30 minutes?
