where i work we have a trade counter for upvc products, fascias, gutters, trims, etc. a guy came back to me today and said hed bought some adhesive from us, i said yes i think i remember, then he pulled out a rusty old cheapo silicone gun, and he said youre mastic broke my gun! so i politely told him that the gun had seen better days, to which he came back with 'i want compensation', i asked why and he was talking to me like sh*t by now. youre mastic has broken my gun and i want compensation and he pulled out a keyline receipt for £9 or sumat and hes adament that i should pay it. i politely told him that we sell them for 3.50 and he aint getting F all from us and he can swivel!! he was slightly red by this point and backing over to his car shouting abuse and calling us cowboys.
