Fountains

Sitting in front of the fountain with 5 gushers (or whatever you call that)

the pattern is
3 will gush
then
4...
then
5..
then
1..
then
2..
3..
4..
5...
and so on.

Approximately there's ten seconds difference before the next gush.

67 guys wearing slacks went by
83 females passed by carrying hand bags

And I'm still here sitting in front of the fountain.
40 minutes and counting....
It was the 20th that day... geeezzz..
