But in your case you still have to pre-select a range of options right? How do you avoid missing the 'unknown unknowns' that a separate service might help provide?
multiple times this procedure led me to dine at fine-dining establishments that i would never consider going into with the clothes i have on (the experience almost always ended up better than i imagined). a nice thing about randomizing is that you become psychologically dissociated from your actions. when things go bad you don't blame yourself and take that to reflect on yourself ("well, i was just following orders"). when things go well you just feel thankful.
