I don't even start answering calls till about 10.30 to 11 and rarely get missed calls before then, except idiots at 3am of course so I would usually decipher at around 1pm. Depends what you put on your profile though obviously.
I start at 11am, but usually get calls and texts from about 9am onwards, but I don't get back to them til I'm ready..
Today was the quietest day I've had in a long time, luckily I wasn't working, was helping a pal moving house but had my phone with me in case somebody wanted to book for tomorrow or later in the week,
could count the calls on one hand!!
