I had to quickly learn the basics of the bartending profession, and at the same time learn to familiarize myself with the bar and my environment. I learned how to make all kinds of cocktails, coffee, cold drinks and beers. I learned how to work with colleagues in a different field from my own, how to adapt to a changing team (after 3 weeks I was the oldest member of the team apart from my manager). During my contract, being familiar with the basics of the business, I also learned how to relate to customers, how to make them consume and build loyalty, the bistro remains above all a business. I also learned the job of waiter to help out when there are large numbers of customers. Above all, I learned how to work under pressure with customers to satisfy, a team that relies on my work and with complicated schedules (16h-2h from Wednesday to Sunday evening).
