The store will usually have its own mobile and the store number, which is a landline. If you want to find the number, just type your storename into google, and give them a ring, my store prefers you ring on the landline usually as its much easier to hear through the store.I got a call on Friday at around lunchtime from a private number, I have a feeling it might have been McDonald's, but since it was private number i didn't call back. First of all, does McDonald's usually have a private number setting, and second, should I call in?
