Unless your friend is in a well and Lassie himself is calling, don't answer your phone while you're in the middle of placing your order.
Today I had a table that started off kind of rude; I said "Hey, how are you doing today?" and got back, "Uh, I'll take a water." Okay, you don't like small talk. I don't either, so let's just put that behind us. Then I brought the waters and the two people continued to chat with each other and didn't even acknowledge me, so I walked away. I tried a couple more times, walking away after being ignored for a good 30 seconds. Eventually they looked ready, so I jumped on the opportunity and went to take their orders. The man wasn't overly polite but whatever, we got through his order. The woman started ordering a salad, her phone started ringing, the man pointed it out, and she answered it. I stood there patiently but intently staring at her, because she hadn't told me what dressing she wanted. After a good chunk of phone call, I turned to the man and said, "I need to know what kind of dressing she wants." The man got her attention and I asked, she answered me, and then she apologized to the person on the phone.
