I left without leaving a note. Bjørn thought I had plugged the toilet and spent part of the evening and the next morning unsuccessfully trying to unplug the toilet.
Finally, today I was able to get a plumber to come and fix the problem. He had to undo the toilet and turn it upside down to figure out that the bottle was stuck right in the track. I am awaiting him to give me the bill right now, but needless to say, this little bottle, worth $5.99 has been a lot of trouble. Oh, and the pain factor of the whole situation was most felt when we had to take trips to Safeway the last 4 days to go #2. NOT fun.
