On the lower floors there is a fancy little turnstyle type thing - you put in a 1 shekel coin and you can enter. However not only does the machine not give change - it also doesn't accept any coins aside from the 1 shekel piece. On the 'departure floor' there is a little old lady who sits at a broken-down cash register and collects payment. As you can imagine there isn't any significant traffic going into the toilet (especially considering you've got to pay to get in.) So the little old lady doesn't really have 'change' for large bills (or even small bills or large coins most of the time - but that's neither here nor there.)
On a number of occasions I've been out of 1 shekel coins or only had large bills and have been unable to access the facilities. Seriously - for 25 whole cents can't you waive the fee this one time - I've gotta go!?! *sigh*
Today I had a wealth of change in my purse and decided to visit the little girls before getting on the bus. On my way out I noticed a chayal forlornly holding a 100 shekel bill and looking at the money-collecting-lady sadly. The look on his face said, "I'll gladly give you this and then go in 100 times - please just let me in" but she wouldn't grant him access, because she didn't have enough change. So I plunked down a shekel, gave him a smile and told him not to worry.
He was extremely appreciative and I felt like I'd done my good deed for the day.
Sometimes it's nice to be in the right place at the right time.
