If people see an obvious use for something, it tends to sell well.
Bingo! Even with something as simple as a bowl, which has a million uses, people seem to need to be told what it's for. I can't count how many times someone has come into m y booth and said 'That's a beautiful bowl, but I just don't know what I'd use it for.' Food, maybe?!? Of course, as soon as you say 'ice cream bowl', they say 'I don't like ice cream'! How about salsa? 'I thought you said it was for ice cream'. AAAAAUUUUUUGH!
Yes! I have two sizes of bowls in my cupboard for daily use. Not once have I said "No! That's only for salsa, put that back and use the cereal bowls instead". People.
