  Mua, Muah, Muas, Muak all are the equivalent of 'Mwah'. Onomatopeiac word for a kiss, ie on the end of a text message or email.
Bees see the world much differently than people do. A small cluster of tomato blossoms won't catch their attention, but a lawn peppered with clover and dandelions sends then into a pollinating frenzy. If you're serious about attracting bees to your vegetable garden, plant flowers.
I'm a Master Beekeeper that has hive at my home 12 feet from my patio. I often sit on my patio eating and drinking while watching my hive. Bees aren't really attracted to most foods, even sugary foods. There is one exception though. They are very attracted to honey, of which I eat a lot.
