They aren't working a 9-5 put it like that!
A lot of them are 'allegedly' deeply involved in organised crime. There's also all the old scams that they've ran through the years: tarmac-ing your drive, roofing your house (accept once you pay, they never turn up to do the job), selling 'real' rolex watches etc.
I used to work in a pub when at Uni, and about a month before halloween they would send their kids into the pubs, dressed in masks, they would run around create havoc, begging, and using the distraction to lift whatever they could. That would normally go on for the whole month of October.
I actually worked at a number of Gypsy weddings as a barman and also as a dj. The weddings never lasted the duration as they were always stopped due to violence etc. and when the fights kick off, every man and boy there gets involved. I've seen 10 year olds chase after a fight with a broken bottle!
The weddings are very much like they are shown in the show, over the top dresses, loads of neon bridesmaid outfits, and they absolutely love reggae music, which is the thing I never got!!
I can say though that they always treated me well, paid well and were polite, but they certainly are not as 'cute' as that show portrays!
