U: Hi there. Can you help me find a train going to London Liverpool Street?

S: What day would you like to travel?

U: I would like to leave from Cambridge on Friday. Any train after 16:00 should be fine.

S: That's leaving after 16:00, yes? Or did you mean arriving after 16:00? If leaving after 16:00, the TR5212 leaves Cambridge at 17:59 and arrives at London Liverpool Street at 19:27.

U: Yeah, that sounds good. Can you get me two tickets?

S: I've booked you on the TR5212, the total fee is 33.20 GBP payable at the station. Your reference number is NJP5V947. Is there anything else you need?

U: Yes, I'm also looking for a hotel called avalon.

S: Sure I've got it right here. What do you want to know about it?

U: Can you tell me if its bathrooms aren’t dirty?
S: The bathrooms are cleaned before guests arrive but at times there has been a missed bathroom cleaning before.
