Coffee shop anecdote: if you make a phone call, you won't have any coffee.

Have you ever had the experience of ordering food from a waiter or lip-synching something to another person while you were on the phone? If you're used to ordering food while talking on the phone, you'll be refused service at Mr. Groom's Coffee Shop in Norwich, England.

Darren Groom, 36, who runs a cafe in Norwich, England, with his wife, 29, has found that people often order coffee while talking on the phone. Orderers often lower their voices to avoid interfering with the phone conversation, and waiters have to judge customers 'requests by "lip reading." This is a big inconvenience to the service, Mr. Groom said."Because customers usually order coffee, we have to ask customers a lot of questions, not just about ordering coffee, such as whether they want to take it away or use it in the store, whether they want whole milk or skim milk." More importantly, he felt that this was a manifestation of whether a person's behavior was polite or not. This behavior was very impolite to the service personnel. Even the service personnel had the right to be treated politely in providing services. So he finally decided to refuse to serve customers who ordered food while talking on the phone.

"This is one man fighting against something that's happening everywhere." (This is a challenge to a behavior that seems to be taken for granted.)
