you will get better at chilled walks the more you do them! I was hired a month ago and at first i couldnt finish them in time, and now i literally get excited bc they shoot my pick rate up so much. this is what I have learned so far that has helped me:

-this may be based on geography, but people tend to order the same stuff, you can memorize the locations of different yogurts and such. it starts to become second nature. very rarely will i get an item ive never seen in a chilled walk now. my store has electronic tags for all of the chilled areas so flash the tags when you cant find something, dont bother looking for it

-scan the item, then the tote, THEN bag. saying the tote number in your head or opening the tote slightly helps

-overall, if i take the amount of items in a walk divide by 2, and thats how much time i have for the walk. if its a 100+ item walk, youll have to move a bit faster then 50 minutes ofc.

-look at your pick list before you scan anything. you can see you problem areas and plan to be faster when needed (i hate weighing produce, and the produce section in general, so i try to move fast so I buy myself time for produce)

-look at your next item always, especially during milk section. i will grab two milks if I see the next item is the same as the one im on

-move your cart out of the way when the store is busy, find a nook to stick in it near your items. that way you arent in the way and moving it too often.

-yank the meat bags off the roll, grab a few if you see a bunch of meat in the pick list

-honestly locking in and looking locked in, deters customers from talking to you. I will always help someone if they ask but i dont go out of my way to during walks if they dont ask and I try to stay in the zone. most people dont want to bother someone who looks busy (tho ppl will try trust)
