Requests are defined as:
1 : the act or an instance of asking for something
2 : something asked for
as opposed to:
Favors that are defined as:
1 : friendly regard shown toward another especially by a superior
2 : gracious kindness; also : an act of such kindness
When asking for a favor it implies reciprocity… not with a request.
It is understood in the business world that the reply to a request can be to AGREE, REFUSE or OFFER ANOTHER POSSIBILITY. If you can’t accept “no” as an answer, you’re making a demand NOT a request!
