I carry it for safety. My bank will back me up 100% in the case of fraud and identity theft. Plus, if I get jumped by Tyrone outside the gas station, what's he gonna do? Run and try and use my card with my white mug in the upper-left corner to purchase some cigarettes and grape-flavored blunt wrappers for his black ass? This is assuming I already haven't contacted my bank, which I would have.
I used to get paid on a debit card and it was BULLSHIT. Unless you had direct deposit, you had to withdraw all of your money off of the card the first time after each payday, or it would charge you $5.00 for every withdrawel in addition to the ATM fees.
I only use cash for the black market.
