Now let me tell you my story, since I haven't been around much lately!
For those of you who missed my epic trip report on another website, I recently spent much of the summer in Germany, India, France, and Germany again for work.
After more than a month in India, I went to France for a few days at
Disneyland Paris with another DIS member before going back to work. Due to the monsoon season, I was rerouted all around India, and it took me 36 hours to reach Paris, soaked in sweat and filth from travelling in 40 degree (Celcius) weather.
On arrival - no luggage. When it did come a day later, both pieces (which were brand new high end luggage, by the way) were soaked with some kind of liquid. All of my clothes in both pieces were damp, and smelled of an odd stench. I had to put EVERY SINGLE ITEM of clothing into dry cleaning in Paris as there was no way I could wear those things. EVERY SINGLE ITEM that I had with me for six weeks of travel.
I have no way of knowing what happened; it may have been fumigation liquids (I know that airlines coming to/from Asia sometimes use them, and we were infested with bugs at one point of the trip). It MAY also have been someone else's pop/soda etc. After three days of travelling in such high heat, whatever had dripped onto/into my bags had begun to turn bad, and the smell can only be described as a combination of mold, chemicals, rot, and any other bad smell you can imagine.
That may be an extreme story, but if YOUR pop bursts or leaks, I don't want it on MY clothes. That has happened to several of us here, not just the extreme form I mentioned above.
