How are gypsies rich?

I work at a hotel and there are always gypsies coming through staying here (always different ones), sometimes they stay for weeks to months or even a few days. They always have nice cars, nice clothes, are always trying to bribe me to keep the pool open late or get them something they need. The weird thing is when they stay, they never leave their rooms so I'm uming they don't have jobs. HOW THE EFF DO THEY HAVE SO MUCH MONEY THAT THEY CAN AFFORD TO STAY IN A 5 STAR HOTEL EVERY NIGHT FOR ENDLESS TIME AND HAVE NICE CARS AND NO JOB@!!!!
