Your implication that some of us are disrespectful is insulting and I don't see where anyone choose to personally insult you for your choices.
As I stated, it's common practice at every pool hall I play at for the employees to sweep chalk dust from the tables onto the floor to be vacuumed up later. Wiping off your tip in that exact seem manner and location is not at all disrespectful or even frowned upon by anyone I know in the business and I'm friends with everyone responsible for that job at every room I play in.
Please don't make false judgements against people you know absolutely nothing about.
Thanks.
I have do this also, But, you are pushing chalk into the carpet not just sweeping dust on it. there is a difference.
