We decided to hire a firm to help us solve this mystery, and naturally the first thing they blamed it on was that the employees need more training and that maybe the kitchen staff is just not up to the task of serving that many customers.
Like most restaurants in NYC we have a surveillance system, and unlike today where it’s a digital system, 10 years ago we still used special high capacity tapes to record all activity. At any given time we had 4 special Sony systems recording multiple cameras. We would store the footage for 90 days just in case we need it for something.
The firm we hired suggested we locate some of the older tapes and analyze how the staff behaved 10 years ago versus how they behave now. We went down to our storage room but we couldn’t find any tapes at all.
We did find the recording devices, and luckily for us, each device has 1 tape in it that we simply never removed when we upgraded to the new digital system.
