google your missed calls
I’m talking a customer through some virus-related unhappiness, and my phone vibrates in my pocket. Could be the guy doing a callout needing an address or something, so I pick up and–
“Congratulations! You’ve won fifty-” Call duration: 00:00:02
If you miss a call, google the number before ringing it back. If you’re quick enough to pick up a spam call, just hang up. Don’t press 5 or anything, just hang up.
Also put yourself on the Do Not Call list, you can register land lines and mobile numbers and it takes less time than it just took me to type this up.
