Reliable, communicative, friendly and non judgemental. Sainsbury's delivery service, (especially it's wonderful drivers) in my opinion are the best of the bunch. I don't mind the odd missing item, and I just don't do the substitutes. Life's too short for angst about a cauliflower...... People just need to confirm things properly on the website and remember shops and phone lines are open if you're desperate for shopping or a row about your fish pie. People complain online because they don't have a genuine cause or the balls for an actual conversation with a human being.
