Jeremy Dyer will be vaping outside in future.
The Governors Bay Hotel owner learned his lesson the hard way after his e-cigarette sparked two fire call-outs over the past few weeks.
The culprit is a new Type-4 fire alarm system which has proved to be more sensitive than he thought.
"Once you set it off, you get the fire brigade at your door 6 minutes later," Dyer said. "They're extremely efficient."
The first incident happened about two weeks ago at 2am.
