Training your staff
It’s common that within your team you will have varying experience levels and therefore different levels of ability when it comes to upselling. Those with more knowledge on the subject can help you and your team in sharing their previous experiences.
Make sure your staff are well versed on any specials or promotions such as a cocktail of the month or deal of the day so they can effectively make your customers aware of them. To help target different areas of the pub why not try a different upsell focus for staff each month? During the summer months it could be a limited edition cocktail jug for example.
