From Fox8Live:

Lee, Henderson and another male were armed when they entered the business in the 1900 block of Centenary Boulevard about 4:55 p.m. Saturday (Aug. 12). At one point during the holdup, two of the three robbers jumped the counter and took a handgun and other items from the store clerk.

While this was going on, the two customers escaped the business and went to their vehicle, described as a blue Chevrolet 1500 extended cab pickup. There, they armed themselves then engaged the robbery suspects as the three left the business.
