Bartenders

Tasks largely resist digitisation. A bartender's shift is building four different drinks at once from muddled mint, chilled glassware and hand-cut citrus while tracking six open tabs and the guy at the end who's had enough — the only pieces software touches are the par-level sheet and the pour-cost spreadsheet, which is why this sits at 16 and not 19.

Hands-on in uncontrolled environments. You are standing on rubber mats for eight hours, hauling kegs and ice bins, wiping spills, changing CO2 lines, and reaching across a wet crowded well that no two nights configure the same way — the environment is unpredictable enough that robot arms only work behind a rail with a fixed 12-drink menu.

Certification preferred, not legally required. You hold a TIPS or state alcohol-server card and dram-shop statutes can put liability on you for over-serving, but the licence that actually matters is the establishment's liquor licence held by the owner — your certification is a day-long course anyone can pass, so it blocks nothing structurally.

The human relationship is the product. Regulars pick a bar because of who is behind it — you know their drink, you comp the third round, you remember the divorce — and that recognition is why they tip 20% instead of using the self-pour wall, though a large share of volume is still one-time tourists and wedding guests who'd take a drink from anyone.

Meaningful discretion. Cutting someone off, spotting a fake ID, deciding when a table's argument becomes a door situation, and calling a cab are calls you make in seconds with real legal and safety consequences, but they run against house policy and posted ID rules rather than open-ended professional judgment.
