You bring home a £50 Jo Malone. Within three burns, the tunnel starts. A hollow groove straight down the center, cold wax around the edges you paid for but will never smell.
You've tried the foil trick. You've timed the first burn to the minute. The wick drowns anyway.
Another jar ends up in a drawer, too guilty to bin, too frustrating to look at.
Add it up across a year, the tunneled Jo Malones, the drowned wicks, the Bath & Body Works jars thrown away half-full.
The number is worse than you think.
