Bryan Christmas spotted several bats flying in and above grocery aisles Sunday afternoon.
"We were getting groceries and went to check out," Christmas said. "We turned around and there were four or five bats flying all over the place."
For weeks, customers have been shooting cellphone video of the winged creatures swooping near meat and deli counters.

The bats had apparently been staying in the lawn and garden section and then appeared in other sections of the store.
"They were going from one side where the meat department was all the way over to the pharmacy and swooping down," Christmas said of Sunday's encounter.
The company spokesperson said the area of the store where the bats gained access was cordoned off, and they've been contained.
After capture, the bats will be released elsewhere. Christmas returned to the store Sunday evening but told us he saw no sign of the animals.
