I can definitely see a few issues with your signage. Somebody somewhere failed to consider that signage would be needed. Since you’ve been adding signage, the ARTM and CDPQ-I look bad for their lack of forethought. Somebody somewhere probably got a stern talking to and now feels humiliated. There’s also the fact that you plastered them on walls that belong to private entities.
Let’s not forget the fact that with a few hours work and very little material, you did a job that probably would have costed tens of thousands of dollars with planning, graphic design, consulting fees, the salary of the guy applying the sticker, the contractor watching the guy applying the sticker, the safety and security officer, and the guy standing there doing nothing, plus overtime pay because it has to happen at night while the network is closed for maintenance.
