Incredibly rude woman there. Slammed my change down on the counter as a way to get back at me for not already having the correct form filed out prior to walking up to her counter. She took enjoyment yelling out "that I get back what I put out." I'll try to update my knowledge on ALL forms provided by the post office clerks from now on, since they apparently should not be expected to relay such information to customers. Customer service is terribly upsetting at this location.
