For the people working on Katie Holmes‘s new movie, Mad Money, in Shreveport, La., TGIF means “Treats and Goodies, It’s Friday.”

The actress has been treating her fellow cast and crew to a tasty surprise every week. This Friday’s special? Snow cones in “every flavor you could think of,” an insider tells PEOPLE.

“We’re always wondering all week, ‘What’s Katie going to do this Friday?” the source says. “The snow cones were great because it’s in the high 80s. They melt fast, but it’s great.”

A snow cone truck pulled up to the set around 3 p.m. Friday, and as word spread among the cast and crew, a line quickly formed to share in the shaved ice and flavored syrup treats that are so popular in the South.

Since shooting began on Mad Money, a comedy also staring Diane Keaton, Queen Latifah and Ted Danson, Holmes has treated the entire cast and crew – about 200 to 300 people – to a surprise.

“The first Friday was smoothies,” the insider says. “Then we had the ice cream, pizza, cupcakes, Coke floats and now snow cones.”

Hubby Tom Cruise and daughter Suri are frequent visitors to the set. Suri was there on Friday without Cruise. “She was walking down the hall today – someone waved and said ‘hi,’ and she just giggled,” says the source. “She’s a happy baby.”
