Call it ingenious marketing or just plain bad taste, but a company promoting its laxatives on a bus stop billboard on busy Avenida Faria Lima in São Paulo has incorporated toilet lids attached to the seats where bus passengers sit and wait to further drive home its message. Those innocently taking a rest while waiting for their rides on public transport unwittingly become part of the ad, which gives off the impression theyâ€™re sitting on a toilet actually waiting for, well, something other than the No. 2 bus line. Questions are being raised about this particular advertising method: Is it humiliating? Or funny? As one of the pictures shows and its respective caption says, some prefer to not take part.
