Event gratuity and Amelia’s tip share

There is a consistent rate, and it is about 17.4% of the gratuity taken on events. It only shows up once two things are handled. First, the gratuity has to be counted from events alone, not from all tips the club takes. Second, the three periods from 16 May to 26 June have to be read together, because an overpayment in one was corrected in the next. Do that and four periods land between 16.1% and 18.7%.

What moves the number most is not the rate, it is how much event gratuity there was to share. Quiet fortnights are quiet because events ran that brought in no gratuity at all, and those are listed under each period below.

Gratuity counts when it can be tied to an event: billed on a named event invoice, carrying an Auto Gratuity service charge, on a tab naming a known event client, on a tab that says it is an event, or carrying the 20% auto-gratuity on a named tab of $400 or more. Everything else is out, so no ordinary table or bar tab is counted just for falling on the same day as an event.

Square records no tips against individual staff. Amelia is not a team member in it and every order logs under the owner account, so the split can only ever be worked out by hand.

The 20% auto-gratuity reaches Square two different ways, as a service charge on an invoice and as an ordinary tip rung in at the till. Only 27 orders in all of 2026 used the service charge, so reading that route alone would miss almost every event.

A gratuity counts in the period it was paid, not when the event ran. The Arc’teryx event on 27 May was paid on 2 June, so its $1,272.70 sits in the following period. Six events in this run moved period that way, and each is marked.
