Doesnt that seem like a lot of employees?
I know an average walmart non supercenter store has around 210 total employees.
There tasks must be very labor intensive
If these are the folks doing the food prep, almost certainly. Have you ever used something like Blue Apron? All the ingredients have to look good, and be packaged into little individual servings - think two cloves of garlic in a vacuum sealed bag.
Times six for the five other ingredients in the bag, many of which are probably more fiddly than "put two cloves of garlic into bag, and place into vacuum sealer."
Times, say, five thousand packages that have to go out and get delivered tonight so people can make their dinner.
The remaining employees will have to work faster and harder.
