Really interesting concept but would love to see more detail than "I'm [name] from [business] and I would like a logo."
What about adding other constraints like style, color, symbols, etc. more in line with a real world brief?
Something like: "I'd like a logo for Slow Roasters Coffee that incorporates our shops color palette of [hex code] and [hex code] and has an urban, upscale vibe that reflects our downtown SF location."
