The retail world has become spoiled. It used to look like this, people would wander in, without an appointment. The salesperson wouldn't know if the client was serious or just killing time. Yet, the hardworking and knowledgeable salesperson gives a thorough presentation each time to the client. Sometimes it's a waste of time, the client doesn't have any interest nor money. Sometimes it's a great use of time, the client is impressed, buys a watch, and tells his friends to buy watches from the knowledgeable salesperson. Today, salespeople are so used to appointments (this small barrier makes someone much more seriously likely to buy something) that they are entirely not interested in walk in customers anymore - because 1, they assume that walk in is waiting for their appointment time; 2, they don't want to upset their colleague by talking to their colleague's client; and 3, they don't know if you're likely to buy anything, and they only want to waste their breath on people who've made an appointment because that barrier to entry increases their chance of making a sale. They'll have to adapt soon though as the world leaves the pandemic economy of appointments and goes back to the pre-pandemic non-appointment ideology.
