"It is with bittersweet emotions that I must inform you all that Gaslight is closed tonight," he wrote.
"I am at the Magic Millions on the Gold Coast and a horse that I have a share in has just won a big race and I have had a few drinks and cannot make it back into work.
"I realise this is highly unprofessional and I have not taken the decision lightly. Rest assured that Gaslight will be open tomorrow for business ..."
Customers appreciated Blake's honesty.
"That's possibly the very best 'sick note' I've ever seen! Congratulations on both fronts," said one Facebook friend.
"Like and appreciate your honest," said another.
On Sunday Pendlebury told the Gold Coast Bulletin he thought he probably would have been sober enough to open the shop by about 3pm, but was glad to have a night off.
"I could have probably made it back up but a few people posted saying it was one of the best sick notes they've ever seen," he said.
The Gaslight Pizza Facebook page is littered with wonderfully to-the-point updates.
Pendlebury's share in Irish Constabulary cost him around $2000 during the course of a year-and-a-half lease.
He made that back at the weekend picking up around $10,000 in prizemoney and bets on the eight-year-old.
"The win sadly was not enough to retire on but I've only had the place open for three months and now I've really got to put my head down and get back to it for the next year," he said.
