I'm also a type 2 diabetic (have been for about 5 yrs) and I get spike like this from time to time. Your Gluco meter reading is just a snap shot of a very small slice of time. Your A1c is a better indicator of whats going on inside of you. I get my labs done about every 6 months or so and even A1c seems to jump around at times.
That meal looks pretty carb-healthy unless that sausage patty is hiding carbs. If they slipped you a regular Coke that would probably jack up your readings.
