Dear Mr. Storms:

When a friend helps us on with a coat, we smile and say 'Thank vou’. If we drop something and someone pick it up for us, we practically burst with gratitude. Strange? Not at all. But it is strange that when we get into business, we take so many things for granted that we forget to say 'Thank you'. Take old customers like you, for instance. You did something pretty important for us - important because you think so much of your business that it gives us а great deal of pleasure to see it grow.

a) enquiry b) reply (quotation) c) order

d) complaint e) advertisement
