I tried to cancel a cleaning because I am coughing up a lung and am extremely contagious. I was told I needed to give 48 hours notice (I was only giving 24 hours notice, I wasn't sick 24 hours earlier). So, I will be showing up tomorrow morning. My apologies in advance to my dental hygienist and to every customer she sees after me for the terrible, chest-crushing cold you're about to get. Rules are rules.
