Yes. I often wonder what they could have done better with the UI to speed up the process for seniors or people who just don't have the patience or interest in all the options they have.
If you don't have an interest in all the options, they have a huge list of defaults[1], and on some machines they have a list of preelected mixes to the side.
I think why people take so long is because it's their 1st/2nd time using the machine, and they want to try out something new. Or in the worse UI choice [2] there's a huge central button that takes you to the mixing selection, and once there its difficult to get back to where you'd select the standard drinks.
