Free booking system that shows customers which time slots are no longer available because they have already been booked

[ad_1]

I am looking for a free booking system for word press that shows customers which time slots have already been booked by other customers.

For example, let’s say usually they can book any hours between 10AM and 4PM, but someone has already booked the time slot for 3 to 4 PM for that day, I’d like this to be shown.

Hope this makes sense, and I hope someone has some specific recommendations.

Thanks so much!
