In Rio Sat., broke my vow to avoid "fast" food, ordered by kiosk (taking 4 times as long as ordering verbally), got message "Something went wrong, start over." Waited for an employee to take my order while one kept loudly complaining about how "busy" they were despite being 2/3 empty at lunchtime. Clearly gave my order for 3, foolishly didn't check my bag because I'd already been there too long & was hungry, had only 2 sandwiches when I got where I was going & one of those was wrong. I was only charged for 2 (over $28 with only 1 drink!), but that didn't help my hunger.
