3:03 PM PT -- A rep for McDonald's tells us they've taken care of the fine with the city of Downey. As for how the whole thing went down ... we're told all employees working that day wore face masks. Once the crowd grew to a large number and social distancing could no longer be practiced, security safely escorted Travis away and the fans dispersed.
Travis' meal has been extremely popular at McD's locations across the country, and we're told some locations have even run low on ingredients since its launch. Travis also released a hugely popular merch line with everything from t-shirts to chicken nugget-shaped pillows.
7:02 AM PT -- A source close to Travis tells us the visit was supposed to be low-key, as he didn't post it anywhere, but his fans found out before he arrived and flooded the location.
Travis Scott's getting dinged for the rowdy gathering at a Mickey D's over his new $6 meal ... but he won't have to pay much more than that to get out of trouble.
Both the rapper and the McDonald's location in Downey, CA have been cited by the city over a whole slew of fans showing up at the fast-food joint last week for the launch of his new meal ... because they didn't have permits.
According to the tickets, obtained by TMZ, Travis failed to obtain an event permit for a crowd over 200 people before he showed up to greet fans who were waiting in line to try his Cactus Jack meal. He also allegedly failed to get a permit to film.
Both citations come with $100 fines, so he's gotta pony up $200 to Downey to square up ... same goes for McDonald's.
As we reported ... Travis showed up to celebrate the launch of his new meal and got mobbed by fans -- many who were maskless and not social distancing -- and had to run for cover.
A spokesperson for Downey tells us cops reported about 500 people in attendance, and the PD dispatched several units to make sure the large crowd stayed safe.
We're told there were no injuries and it doesn't seem like any arrests either, so the only McDamage is to Travis' and Ronald McDonald's wallet ... but it ain't much.
BTW -- Scott getting his very own McDonald's meal is a pretty big deal ... he's the first celeb to have one since Michael Jordan back in 1992.
Order the Cactus Jack $6 deal and you'll get a Quarter Pounder with cheese, bacon, lettuce, pickles, ketchup and mustard ... medium fries with BBQ sauce ... and a Sprite.
