So she walks out on a date just because dude used a groupon (I need to find out about these)...this is not a good sign. Unless u ballin and don't mind trickin and simpin for chicks...she gonna be a headache to deal with. U got plenty of folks in this country who have horrible credit, no money in checking/savings acct to account for any emergencies, u got folks underemployed or working low paying jobs, and people who don't have enough for their own place, car or to maintain their vehicles...if anything..I would think positively about a person who cares about saving money and being disciplined with their spending. The only thing I can see a woman looking down on a man or person who is cheap is if they are unsanitary, never wanting to do anything, or clearly spending on themselves but not on their gf.
He needs to consider himself lucky that broad walked out because if he dont like simpin or ain't ballin...he gonna be miserable.
