Dear Sir or Madam,
I am a student in a business school and through my research paper, I conduct a study on the communication of companies like McDonald.
As a client or former client of McDonald, I invite you to respond to this questionnaire. You only need a few minutes, which will be very useful to complete my project.
Clarification, my memory is not related to any particular brand. In fact I realize other studies on other brands (so I'm not working for any brand). Responses are anonymous and kept confidential.
Thank you in advance for your participation.
