This is exactly why I didn't want to give the client my mobile number.

It's a Sunday morning, and he's messaged me asking for me to do something today.

Hopefully by boss is sympathetic with the week I've had and lets me ignore it.

I charge three hours initial rate on weekends. Even if it's a 10 min job.

And double(or more) rate per hour after that.

Put that on the invoice come Monday, and most customers stay away from calling you on weekends.

Take care of your spare time people!
