(OP) its hard to have an exact percentage because it's (crude) observation - I could totally go with 2.5%. The number is in the low single digits for sure, but definitely higher than a rounding error (or a null-hypothesis). Whatever the number is, it's high enough to impact the people that have to interact with lots of other people - they feel it, which is really what I was getting at.
