After several practice instrument approaches into Lakeland, Florida, I stopped and headed to the restaurant. Later, when ready to leave, I called ground control:
"Control, ready to taxi VFR to X39."
Ground (chuckling) :
"Cessna Three Four Five, it would be quicker if you flew, but if you would rather taxi, I-4 is just up the road. Cleared via taxiway Bravo to Alpha Three for departure."
Me (somewhat embarrassed) :
"Ah ground, Cessna Three Four Five cleared by Bravo to Alpha Three. And I think we'll fly."
