Put them in a hash in the first place.

class Customer
  def initialize 
    @data = {
      'Customerid' => nil,
      'city' => nil
    }
  end
  attr_reader :data

  def method_missing(id, *args, &block)
    possible_key = id.to_s
    is_setter = possible_key.chomp!('=')

    if @data.has_key?(possible_key)
      if is_setter
        @data[possible_key] = *args
      else
        return @data[possible_key]
      end
    else
      super
    end     
  end
end

c = Customer.new
c.Customerid = 'Alfki'
c.city = 'Belin'
p c.data

>>> {"city"=>["Belin"], "Customerid"=>["Alfki"]}
