i'm just learnin' doin' the neutron dance(the man has a stepladder. he isn't using it. he's examining it. he's doing nothing so intently i'm loathe to interrupt him. but he's the 1st clerk i've come across, so:)"excuse me? hi. i'm looking for someone to cut some wire for me. do you know who i should talk to?"
"you've done the right thing. i can handle that."
(motions for me to proceed him the the wire spools)
"i bet you know what kind you'd like too."
"yes. 20 feet of the green ten gauge, please."
"ok. now. is this for something fairly low voltage?"
"oh, i hope so. i'm using it to build puppets."
