| Scale of the drawing | None. A rectangle is whatever size you stretch it to | Real millimetres. The room is drawn once, at its own size |
| Service clearance | Judged by eye, or discovered on the day of the set-up | 1.50 m checked as you drag, configurable per venue |
| Space per diner | Not calculated | 0.60 m minimum per chair; warns below that |
| Columns and doors | Drawn if somebody remembers | Real obstacles: no table can end up on top of one |
| Guest list | In another file, reconciled by hand | The same list, seated on the plan |
| Menu counts | Counted by hand every time something changes | Comes out of the plan itself, with allergies and children separate |
| Last-minute changes | Redo the count and send the file round again | Move the chair and the sheets redo themselves |
| The couple | You send them a PDF and they answer on WhatsApp | A link with no sign-up: they place their people and can’t break the set-up |
| Who can touch what | Whoever has the file can change all of it | Owner, staff and client, each with their own |
| The good version | «plan_final_v3_FINAL.pptx» | One, with the date it was signed off |
