...really, really loud..can't hear it in the vid..this was AFTER he had been woken up..then he fell back asleep and was snoring again, less loud, but still noticeable..nobody did anything about it for a while..finally an employee nudged him..and he groggily looked up..didn't seem to care that the whole library was staring at him & the snoring drama ..went back to sleep again..another employee nudged him again with a little more stern warning..
