As a customer, I always like to get more than I expected -
Also as a customer, I won't complain if the clerk cuts to the thread - as long as the thread is on 'my' side and the cut is straight. I will, however, complain if a cut is only 1/4 inch short! Especially if it's on several cuts.
But do I call and say - Yippee, I got lots extra! - No. Do any of you?
Funny - if we go to the butcher, we don't expect to get 18 ounces of ground beef for the price of 16 ounces. Wonder where we got this 'we expect/deserve extra' when it comes to buying fabric.
