Choosing from the bottom of the pile was a big mistake. The entire pile toppled. Some watermelons bounced all over the place and hit the parked cars besides. Some watermelons were smashed opened. It was a total disaster.
The culprit (facing camera). The store owner was kind enough for not asking us to pay for the damaged goods. It pays to be a familiar customer.
Finally, we only bought 2 good ones. As usual of watermelons here, they were big, juicy and sweet.
