TIEN - Tour Guide in Paris

First of all, the reason I sent the final confirmation the night before is because, in my experience, many guests confirm one or two days in advance but later change their plans at the last minute. This happens frequently. That is why I need to reconfirm attendance as close to the tour time as possible. If I confirm too early, plans often change again, and unfortunately there is no reliable way for me to prevent that. Secondly, you mentioned that you traveled across half of Paris to attend the tour. Realistically, that means you would not have woken up just 20 minutes before leaving. You must have had some time in the morning before departing. During that time, there was an opportunity to check and respond to the confirmation message. However, I only received your confirmation 10mins before the scheduled start time, rather than earlier in the morning. I am not able to wait on-site without a confirmed response. There are simply too many last-minute cancellations, and guests are not required to take responsibility for them — they can cancel easily, while I would be the one losing time and energy waiting. In addition, I had provided my contact details, including my phone number and WeChat. You were welcome to add me or send me a message directly if needed. I also shared the itinerary details in advance. Unfortunately, no additional attempt was made to reach out. I hope this clarifies the situation from my perspective.
