This is a common problem in the bartending world. Most bartenders don't realize that you don't want to muddle mint while making a mojito, or any other cocktail that requires mint leaves for that matter. Mint leaves only need a light press to release the oils to flavor the drink. When you muddle the mint it brings out a bitter taste that overpowers the natural mint flavor. So, the next time you make a mojito - go easy on the mint!
As bartenders we are occasionally the line of defense for beautiful women that sit at our bar. Over the years, I have developed signal for women to let me know a customer may be bothering them (that will go unnoticed). If anyone is bothering you or being to forward, simply take your cocktail Napkin out from underneath your drink and slide it to the edge of the bar On the Bartender side. It is easy to notice and then it gives me the opportunity to engage and assist.
Always be diplomatic and courteous never trying to embarrass anyone but just resolve the Situation with class.
Tip: Always placing a cocktail napkin underneath the beverage sends a message that you are a professional and organized Bartender.
If you have heavy humidity, and are having trouble with the napkins sticking to the bottom of customers glasses, throw one shake of salt on the top of the napkin. Now the beverage napkin won't stick to the glass.
*Don't go overboard though because your bar top will look like a shuffleboard table.
