Even though we've been in our house for over 6 months now, we've still had a steady procession of tradies visit for varying reasons. If they are here for any length of time, we'll offer them a cuppa and something to eat, if they feel like it. Many, many times, we're met with a reply along the lines of, "No-one ever offers me a cuppa!"
Are DW and I the only two remaining decent people on the planet? Of course not, but how welcoming are YOU to people who you insist on visiting your home to repair or install something?
