customer: we need you set up a logo for embroidery
me: no problem, fire me over vector art
customer: no problem... done. i just emailed it to you.
me: i just imported your 'vector' art into some graphic software - it's not vector art
customer: yes it is. i sent you an eps file - that's vector art
me: you are wrong. you took a crappy/grainy jpg and exported it using software as an eps file. this does not magically make it vector art. it's still a crappy grainy jpg
customer: but it's an eps file.... that's vector art
