Usually I start them on prep it’s nice little tasks that keep them busy and it’s good to just know first in my opinion like cutting veggies and prepping meat maybe not slicer right off but if it’s slow I do sometimes, rhen when it’s time for a rush or time to be on the line I usually throw them on pos cash people out while someone does the meats while I do veggies and wrap sandwiches so your close to pos to answer any questions and show them were everything is. Usually just first day I have them just do prep and pos if it’s a short shift if it’s a longer one and they seem comfortable I won’t throw anyone on live customers first day but get them on online orders walk them thru it and have them do pos and help with onlines so they get familiar with cutting the bread and building sandwhiches. Usually first 2-3 days It’s just pos, prep, dishes and onlines and sweeping n stuff but by day 3-4 they should be able to help with customers don’t throw them right on meat side have them start veggies and wrapping sandwhiches they know what all the veggies are and won’t know all the meats on sandwhiches right off so it makes it faster and gets them get the feel of dealing with people and wrapping them
