Wear Something Unusual
In this study they used female servers, some wearing flowers in their hair, some without. They found that those wearing the flower had an increase in the average tip received.
Will this work for you? Possibly, if you’re a female server in a casual restaurant.
The key here is to be conservative. You want to wear something that does not scream “Look at me I’m a clown”. Look around at your guests, do you want to earn their respect or to have them laughing at you.(laughing with you is ok but not at you) Don’t go overboard with the bling bling, the flash, the sparkle. A simple brooch, tie tack, performance award pin or a nice tie will do. Make it something that the guest will notice and possibly comment on, but don’t have it screaming at them.
When is the last time you asked a server what all those pins they are wearing on their uniform where for?
