Since we are on a public forum and all I wont go into to much detail... But the other night this guy was up my a$$ about a main and wire his "installer" laid underneath some sod 10 years ago or so... First he tried to tell me my company installed this system..I laughed at him... Overloaded zones 10-12 pgps on a 12 gpm 35 psi POC. For over 200$ worth of repairs he kept having me chase areator holes in an hacked main..He was wasted and treats his wife like trash. His wife is a really nice woman who loves gardens and plants.. After 7 pm or so I said that's it....He tried to have me keep going fixing the mainline repairs..I said if he wanted anymore fixed he would need to go to homedepot and do it himself.. I have dealt with this guy for 5+ seasons and he gets worse and worse.. With people like this I don't hold back.granted I don't swear and talk nasty but I don't take his sh!t, and when I leave I pray its the last time I'm going there. How do you all deal with them?
