Time is of the essence for professional shoppers

Periodically I shop professionally for the flower shop.  Today I went to purchase items for two gift and flower baskets.  One of the baskets was a timed delivery.  It was scheduled to be delivered in early afternoon.  I had adequate time if I used my time wisely.  I have to use strategy when I professionally shop.  I walk swiftly...in this case choose items from the trail mix and nut aisle and then proceed to the produce section to select unblemished apples, pears, kiwi, oranges, grapes and tangerines.  I have to work my way around lackadaisical shoppers who apparently have all the time in the world and can afford to meander about the store aimlessly.  I met at least a dozen today.  I used the self scan computer to check out and then pushed my cart out of the store and loaded the goodies into the car.  I pulled out of my spot and waited as four teens dressed in batman costumes walked as sloooooowly as possible in front of the car, preventing me from pulling onto the main road.  I don't have time for poky indecisive customers and even pokier unaware pedestrians.
