What the spreadsheet misses

Keselamatan
Fewer heavy trays carried across a busy floor; robots are a trip hazard for guests who are not looking.
Kualitas
Hot food arrives at robot speed, which is not fast.
Fleksibilitas
A runner also refills water, clears and charms.
Edge cases
Narrow aisles, steps, outdoor seating.
Customer experience
Novelty helps family restaurants and hurts fine dining.
Jobs and redeployment
Typical use is fewer runner shifts and servers spending more time at tables; tipped wages make the US maths odd (the BLS median includes tipped-wage states).
Regulasi
None specific; food-hygiene rules apply to cleaning the trays.
