Grumbler, when PLEASE comes in the beginning, the speaker is imploring the listener. Like <I beg you>.

Я помню, но когда речь идет обо времени смысл вроде всегда такой.
Можно сказать более сильно "еще 5 минут, ну пожалуйста".

If you put PLEASE at the beginning followed by a noun phrase, the Russian has to be very emphatic and pleading because the speaker is literally begging for that thing. 

But I have a feeling that Sophia made this sentence up and applied Russian syntax for the word “please” and the number five written numerically.

Perfect
