First off, who knew Target stores in Hawaii sold lychee? Must be quite a few people knew since Target is now monitoring lychee sales upon checkout. Yes, Target cashiers watch how much lychee you’re buying.
And don’t think you can outsmart the system by going to self check-out. The POS systems are programmed to halt your checkout until the on-duty clerk checks and approves your lychee purchase. Simply put, don’t hoard the lychee.
