Since you stayed 10 WHOLE MINUTES in the museum for the 45 minute tour, then you are a typical expert on what you saw. The half of the museum that you ignored, and didn't even see the demonstration on, was 1,000 kilos of grey minerals that become the Colors of Fluorescent paint when the lights get turned off and the UV lamps get turned on. You have about as much interest and patience as a Baby.

What is Rude is a member of the "Telephone Generation" like yourself writing that No Cancellation Emails had been received - when you and every one of these "Waste of Time" complainers had received a Cancellation Email Automatically from Appointy. Again, Every cancellation has a Cancellation Email Automatically sent from Appointy whether you want it or not, or in your case, whether you look at your emails or not. Amazing that you and all the other "Waste of Time" complainers who are physically fused to your smartphones Did Not see the cancellation emails sent to you automatically from Appointy - when you look at your phones 125 times an hour - waited outside for no reason, and then complained on this site that you didn't receive cancellation emails(!) One Artist who is 62 years old built and runs this museum for twenty years -myself- and when he is sick he cancels appointments, and for the tenth time: Cancellation Emails are Automatically sent by Appointy to all visitors who made an appointment.
