A customer-service trick called addressing the tinge: tell customers you'll review their order, then secretly finish it early and call with the good news. The surprise beats the doubt they had going in.
'We want someone to review your order, but if it's an inconvenience, please tell us and we'll expedite it immediately for you.' That's how you address the tinge. Then here's the magic. You prepare the order just as you did as quickly as possible, but now an hour later you call a customer and say, 'Hey, we have wonderful news. We said we get it done in 10 hours. We're able to expedite. It's been reviewed. It's perfect. It's ready to go. We're ready early for you.' And your customers will be blown away.
