As a trucker I get approached frequently by people while parked 9-10 they ask for money cuz they're out of gas have kids in the car etc.. I offered once to put $20 gas in car for lady she got pissed when I wouldn't just give her the money.. most of them are drug addicts drunks or con artists... there's a lady in laredo tx that begs at an exit ramp off I 35 looks pathetic dirty and sick.... locals told me she drives a lexus has a nice house with a pool not far from where she sits and makes $3-$400 a day from suckers... sadly most of the ones you see holding signs are just like her.....
