Must be fun to hang out at bus shelters in the U.K. Sometimes they assault you with the smell of baked potatoes, courtesy of McCain. Or they try to ruin your diet with the promise of free cakes, from snack brand Mr. Kipling. The latter is back with a holiday campaign from JWT London promoting its new Mince Pie and Black Forest Whirls Christmas cake flavors, via holiday-themed cake shelters and billboards that distribute free slices (in resealable packs, which the brand is also promoting) at the touch of a button.

Even the calorie-counters can partake in the fun, since the installations also emit the cake aroma and play a specially recorded version of "We Wish You a Merry Christmas" by the Salvation Army, which gets a donation per dispensed slice.

An accompanying campaign, "A Miniature Kipling Christmas," features miniature sets of people in various Xmas settings. Check them out on the right.
