If I have to say it will be 10. I have more than 20 years of experience in sales so I deal with all type of customers throughout those years. So people they want to buy, it's an easy sale and it takes you maybe 10 minutes to do everything for them. The medium customer which is the one that is not really convinced and the very hard customer which are the ones that I love because basically you need to probe, you need to ask questions, you need to see what the cues that the customer is giving you and based on that you can build something around those little cues that they give you. Every customer wanted to buy a product if they're calling it's just a matter of probing and ask so I'm a very good at what I do, if I have to say so myself. Thank you for the question.
