Do wi-fi hotspots use automatic throttling?

Tried downloading a 30mb file while connected to a starbucks wi-fi hotspot. Initial speeds showed about 100kbps but in less than 5 minutes it dropped below 5kbps so I just cancelled it.

Could be, or maybe more people joined/started downloading also. They don't have unlimited speeds..
