I'm wondering if it's worth tipping when you place your order so you get your food while it's still warm?
And, if you do tip before hand, rather than at the door, and get a rubbish service can you remove the tip? I genuingely wouldn't but was wondering about that.
Before I get called lazy, I have a broken ankle so the front door is about as far as I can go when we haven't got any shopping in.
