<prompt> Human: So I called a chain waxing salon for a service, and while on the phone, they told me they need to have my credit card info on file. Ive been serval times before and never had this request. Why? I dont think its a good idea and I dont understand why they would want it. Im leery of this. Anyone have any insight?  <response>: Sure, my insight is to say no.x200B;They have no need to have it on file.
