Taxing Tips in Error

I have a live site with your plugin installed which allows customers to give a tip to the bakery at checkout. Pretty brilliant feature. However, I’m having a small glitch with the plugin.

The option: “is taxable” is turned to off, but the tip is still taxed.

The only thing I can think of is that I’ve created tax rules that are used on some products and catch them in the functions.php file for processing. This .shouldn’t. effect anything because it catches only products labelled with specific tax classes for some regional quantities rules.

Going through the functions.php file with a fine tooth and comb, I find the lines:

if ( $item_tax_class == 'six-plus'  &&  $item_tax_status == 'none'  ) {
                $cart_item['data']->set_tax_status('taxable') ;

But again, this shouldn’t catch it because I doubt the order-tip tax class was coincidentally also given the tax_class of ‘six-plus’.

Any help solving this?
