I plow a Target,a Lowes,a K mart,and the old Target plaza which now has a Hobby Lobby a Hastings in that building with a new large Groc. store attached.Each is very diffrent as to the flow of traffic.Arrival times are much earlier for the Lowes which is a Home Depot type store, the large groc. store has issues with shopping carts performance on snowy isles,the large department stores place alot of urgence on their loading docks.Each is very diffrent in reguard to the level of service required,either because of the number of customers they handle or how they see snow removal fitting into their budgets.I have also had som real issues with manager turn over.I lost the Sams club that i did because of the constant turn over of their managers. New manager were not happy with the job we were doing but it was all the previous manager was willing to spend and all that had been agreed upon. Despite all of that, we really like the big store because we are usually providing them service when are servicing no one else but the local airport,despite the diffrences in service levels it still is usually higher than other stores.
