Step 1: Add up the cost of the spinach salad, tuna sandwich, and 2 glasses of lemonade.

$4.40 (spinach salad) + $6.25 (tuna sandwich) + $1.75 (lemonade) + $1.75 (lemonade) = $14.15

Step 2: Add the tax to the total cost of the food and drinks.

$14.15 (total cost of food and drinks) + $1.40 (tax) = $15.55

Step 3: Subtract the total cost (including tax) from the amount Roger and Karen gave to the waiter.

$20.00 (amount given) - $15.55 (total cost including tax) = $4.45

So, Roger and Karen should have received $4.45 in change.
