One word card collection

Q:

I used the Metro Cafeteria as renovation work began on the Central Cafeteria, but it was difficult to pay with school cafeteria money because cell phone reception was not available depending on the carrier.
Even if barcodes are prepared in advance during busy times, there is a risk that the validity period will expire, making it difficult to deal with the situation.
I would like to request measures such as improving Wi-Fi in the Metro Cafeteria.

A:

We have started considering installing event Wi-Fi from a carrier with relatively strong signal strength to get through the renovation period, so please wait for a while.
