Should you use a form or WhatsApp?

Yes, WhatsApp, if on that shift someone reads it and says whether there is a table. No, a form only if the message gets lost and the booking sits written on a page the floor looks at. Write to the number at the hour of the ad and see who replies. The form asks for an email address and nobody calls, or the chat opens and there is no reply. The destination tested, message or form, with the name of who closes the table.
