Those who live by the tech shall die by the tech

Menu screen at Hudson's Bay Company restaurant, Vancouver, BC

Having your menu on a display screen is great. Prices and products can be easily updated. You don't waste a load of money when you print up signs only to have to get rid of them a few days later. And typos can be corrected immediately.

But if you depend on technology then you have to be prepared to deal with the inevitable failures. About once per week I see an electronic sign that has "crashed". Not at all surprising, but frustrating for both the customer and the retailer.
