 In many cities, for example, like if you're an older person and wants to get a ride to a doctor's appointment, you know, using transport, you know, if you have to use public transportation or, you know, access a ride, you know, you got to call a number, you know, you got to do it two days in advance. Can I call back the day before the appointment, you know, with this pickup window, you know, wait outside, hope that this van or bus shows up.
