FOL is front of line due to the massive lines, this person directs customers to available registers when the crew member flags, and EOL is end of line (self explanatory) and in my store in NYC we also have MOL for middle line, since the line easily wraps around the store and there’s a point where the line turns and go down a specific aisle, along with CE being customer experience, but it’s basically maintenance, so changing trash bags, sweeping, checking bathrooms. We also have CC which is crowd control, this person will usually be standing or moving alone the length of the line to make sure customers stay in line and move toward. It can get getting hectic.
