The latest tool for the modern pick-up artist:
fake ATM receipts with unfeasibly large balances written on them.
Next time you meet an attractive gold-digger type in a dive bar, jot your number down on one of them (which you happened to have in your pocket; note: don't pull out a pristine new roll of them or you'll blow your cover), and when she (or he) sees "your" balance, they'll call you back straight away.
Though if you're going to do that, why not
print your own?
