When I purchased a $7 car wash & went to use it 4 days later, the code printed on the receipt came up invalid. The attendant couldn't do anything about it, stating the owner would take the $ from her pay if she helped me. I left a written message that day for the owner, & got no response. Over the course of 7 weeks I've left 7 messages to no avail. If this owner has no qualms of keeping my measly $7, than what else would he do? Do not trust this man, & I would NEVER give him my business again. I drive by there every day on my way to a different station to gas up & get drinks. I'd highly suggest you do the same!
