Commandment Number One in sales: ASSUME THE SALE!
This includes selling yourself, the appointment, your company, your products... everything. It is not a rule, it is not a suggestion, it is not a business practice. It is a commandment. If you don't do it every single time, you don't deserve to call yourself a salesperson, because assuming the sale is what salespeople do.
How many times have you heard this: “Would you like to schedule an appointment?”
Wrong! WRONG! Of course they want to schedule an appointment, because you are a great person, you work for a great company, and you have a great product. With that in mind, this is the only reasonable question:
“Which day is best for you?”
