**ok sure, thanx
i was flying Gulf Air from New York to Delhi via Frankfurt and Bahrain. when i arrived into JFK from Toronto and to my surprise i was told that i had no onward reservation. i got reallly mad coz i had already commenced my journey and how come they had my reservation in Toronto and not in New York. i had to wait while the manager was looking everywhere frantically to find my reservation. anyhow, he found it just in time on another system. most people had already boarded the aircraft. the manager tried to please and upgraded me to Business Class.
now, i had a couple of hours at Frankfurt and since my journey doesn’t end in Delhi coz my destination is 650 kms away which involves a train ride for 7 hours, i thought its good idea to take a shower, the facility was there. so, i jumped into this high-tech ultra mod stand up spacious shower. there i was in my Birthday suit, and i couldn’t turn on the shower coz there was no knob in sight to turn on the shower. i stood there all sad thinking that i wudn’t be able to take the shower…lol…then i just happened to raise my arms up in the air and VOILA! it happened…the shower turned on…and i, finally, had my shower…thanx to Allah 
the shower operated on motion detector device!
