About the separate registers inside the big grocery / dept stores

from Mary Myers:

OK this came up so I thought I would add it. If you are shopping in Lottemart or oulet stores, there are different registers for each little store. For example in Lottemart if you're buying from a clothing outlet inside the store, you need to pay at the register there and not the Lottemart register. You'll see a checkout inside their area.

This doesn't apply to the grocery area of course ... but if you are buying clothing or cosmetics be sure to check if there is a separate register.
