My car battery died in the nearby Sprouts parking lot today so I walked over to go buy a new battery. Mike was extremely helpful and even installed the battery for me, he was absolutely amazing! Please give that man a raise he was so genuinely helpful and he went above and beyond. Shoutout to Mike, you're awesome!!
