If someone starts a conversation with you and then asks you on a date, you have no obligation to tell them anything.

However if a person driving a Ferrari wearing a 5k suit and a 50k watch asks someone on a date, that person may be under the impression that they are going on a date with a rich person and that they will not be going to McDonald's.

I'm not saying that there is anything wrong with taking your date to McDonald's. Plenty of people love McDonald's. But it is not the same thing and that date may not go well.
