I may sound petty but I hate getting ripped off or tricked. We bought 2 sandwiches (3.75 each) which should be $7.50 and assuming with tax, it should be not a dollar more in taxes. However my total came out to $8.62. The man doesn't give out receipts and do not take credit cards meaning IRS can't track how much he really makes. Unless taxes are 15% in Charlotte, I don't know how it came out that much. Usually I would buy 5 or 6 so I don't really pay much attention but this time, I was really able to calculate. If the sandwich is $4 and not $3.75, he needs to stop being shady and update his signage. The  man is rich. Cash only is shady business. No receipt for customers to see break down of your purchase. Super shady.
