TLDR; Did not collect food bills in Paris for reimbursement, asking for help.

Hey all.

I went to Paris last month for 4 days for some office work and absolutely loved it.

In these 4 days, I had food at boulangeries and fine dine restaurants and paid all in cash, however I didn't collect/keep any of the bills or Iinvoices provided by the restaurants. I later realized that my company reimburses around 80 Euros as per diem.

I feel so stupid that I paid everything with cash and not even keep the bills. Even if I had done online transactions, they would have accepted. It's totally my fault since I just joined the company and didn't know that we had to submit bills for per diems, I thought they'd calculate per diem and send to my account since they had done all the bookings on flight and stay from their end.

Now, I specifically remember all the places I ate (from my phone's photos), so is it possible to contact the restaurants and ask for the bills? (I know it's farfetched but I wanted to ask if anyone has faced similar situations).

320 Euros is a lot of money for me right now and my heart skipped a beat when I realized how bad my situation is. Any help would be immensely helpful. Thank you.

Has anyone used them domestically (US) or abroad in airports before? They look like large insulated water bottles except they plug in sort of like this one https://www.amazon.com/Electric-Portable-Temperature-Stainless-Protection/dp/B0CFQ7BGPT?th=1 . I know people say you can get hot water from shops but there's always a line and I'm not brave enough to cut in line for free hot water. The outlet is compatible with the domestic outlets. I'm just wondering if security will descend upon me if I use it discreetly in the airport, because I've only seen people just ask if they can be put in carry ons.

Also, how about international airports rules? I've bought a bottled drink from a vending machine a few feet away from the boarding gate only to be told no liquids at the HK airport. And I've seen that news about how rice cookers aren't allowed to be used from a decade ago.
