Being in biz automatically exposes us to stuff exactly like that, I have had more than my share already this yr and in fact just fired a particularly angry old lady customer who wasnt worth my time. (Terribly sorry due to scheduling i will be unable to yadda yadda) Also, I just started selling in a subdivision with very small lawns at @25.00 per cut when there is already someone working the area for $15.00. Surprise surprise he does a bad job. I expect to do well in that area as people get to know me. With a call like that remember that every minute you think about it you give power to a dipspit. You are right, It is funny and thier message should be laughed off.
